I know a lot of people get fundamentalists and evangelicals mixed up (speaking of American Christian movements). They do tend to be more or less aligned politically.
I am ambivalent about these two groups for different reasons and, as a non-Christian, I feel that evangelicals do more to give me a positive feeling about Christianity... while at the same time being really irritating.
This is a simple light-hearted guide for non-Christians to tell these two apart by their immediately noticable pros and cons.
And yes it's very generalized. It's not really intended to be super-accurate. It's more of a semi-humorous look.

FUNDAMENTALISTS:
Pros:
*They tend not to bother you because they really don't care and figure if you're chosen, you'll just decide to convert.
*They don't really care much about adding things to school/public life (ie Intelligent Design, oraganized prayer time, etc.)
*They sometimes give to charity, mostly so that they can justify shutting down the government, which they fear is out to destroy Christianity.
Cons:
*They seem to care more about hating things that aren't Christian than liking things that are. They're about as pleasant as a root canal.
*They're very mobilized in political movements to remove tolerance of anything that doesn't fit their interpretation of the bible (ie gays, other religions) or their belief in what a holy culture is (ie other cultures)
*Tend to be pretty harsh and black & white
*The above-listed pros, while convenient, are mostly a result of their not giving a $%!^ about you at all. They're more likely to hate you forever (unless you're family- then they reluctantly put up with you) if religion ever comes up in a heated converstaion.

EVANGELICALS:
Pros:
*Very nice. Frightfully nice. You can't really dislike them no matter how irritating they are.
*More tolerant of other religions and cultures.
*They really care. They give to charity out of actual concern and annoy you constantly because they want you to be "saved".
*Less concerned with removing things they disagree with from society (with the notable exception of anything that involves killing- ie abortion, the death penalty; in the past wanted to remove evolution out of fear that it would influence social darwinism)
Cons:
*They will never stop hounding you about religion and will bring it up at very interesting times.
*Obsessed with the end of the world
*Motivated to add things to public/school life (ie Intelligent Design, organized prayer times)

Yeah, yeah. So in my experiences I've had a soft spot for evangelicals and generally find fundies to be irritating people. I went through a subphase of each back when I was in my Christian phase. It reminds me of Jimmy Stewart in Harvey:
"My mother said that to get by in life, you need to be oh-so-smart or oh-so-pleasant. I've tried both. I recommend the latter."

I can overlook the annoyance factor of the evangelicals because they're nice. They use the honey approach. Fundies on the otherhand are scary. They leave you alone... but you always get the feeling that they're plotting some kind of attack when you're not looking... and they're not so nice.

Georgia is filled with both. The two have a lot in common, so it's tough to tell them apart sometimes. But there are some differences. For me, fundamentalists tend to be more political oriented and hate filled. They are the true theocrats and really are a scary lot. Evangelicals tend to be "God oriented". They love to push their faith, but aside from that are more likely to leave other people alone. They are more concerned with getting to their version of heaven than fundamentalists, who seem fixated on recreating the world in their image.

There, I said it. If you're offended, I don't care. Fundamentalists have been bringing down the noble and holy religion of Christianity for far too long. It's time these people were shown for what they really are: hate-filled, insecure, self-righteous Pharisees who do nothing but push people away from God.

Man, that felt good!

aren't these loose terms used by secularists? I don't find many people in society referring to such religious profiling unless secularism is involved.

They are loose terms. They refer to two very broad religious movements, both of which are growing (especially evangelicalism), and thus important social movements. But of course most Christians belong to neither group last I knew.
The terms are not as loose as merely "Chistians". A lot of people will point out elements of either evangelical or fundamentalist movements and refer to them as "Christian", which ends up being inaccurate and often confusing/offending Christians not belonging to the same type of philosophy. To study a movement, there is trade-off between genarality and specificity. You must be specific enough to avoid blanketing too much and general enough to have meaning.
Of course within the movements are many different sects (especiallyy in evangelicalism), but they have certain common factors that seperate them from fundamentalists and mainstream Christians.
Fundamentalism is found in all major religions... but I think evangelicalism is found strictly in Christianity.
