I agree with you - get loud - get passionate - but don't get stupid!
I'd like to add one more thing.
Politically correct argumentation is not stupid, in fact. It's perfectly rational. But it's not fair. It's well done propaganda in fact. Believe it or not, commies used and are still using the same ways. It's a softer form of brainwashing. They will try to deform your way of thinking by twisting the common words. Hard to explain that properly for me.
And even people who are not yet fully contaminated do adopt the "mainstream" ways of social interaction because the others expect it and would get either confused or angry when adressed another way.
A very good example of that is ever present tendency to selfcriticise. Commies loved to make people criticise themselves, as well as traditional Christian church did. Mea culpa, mea maxima culpa. Like that.
Today we feel that it's polite to approach the "sensitive" conversational topics - or just to present ourselves - this way. May be either a way to soften the overal feelings by giving a clear signal that we are on the "right" side and we will not enter the real argument and verbal conflict, or whatever.
An good example is what McCain said after losing the elections: "You did great, people, it's my failure." Now that's obviously a lie. Was he saying he didn't do his best to win? Did he mean he was not fit to be a good president? So WTF?
The same thing is the very popular criticism of one's own nation and people. Like "We [add a name of a nation here] are [add a degradational remark here]". First of all, this is obviously not true, since the people are basically the same everywhere. So why to mention some obvious human vice and pretend it's nation specific. I don't want to be personal (because you just used what is generally accepted as a polite way of expressing yourself and I take it as a politeness from you) but I want to use the "American way of arguing" as a good example. It's not typicaly American - it's simply stupid and so very international - people do it everywhere and all the time, because people are, plainly, mostly stupid.
Commies supported that a lot to make people in their empire feel less territorial.
That said, I know that one would - if the language barrier is missing ofc - understand better people with similar education and social background than his fellow citizens from different social level. But this is not the point of this. The point is a high level propaganda alert.
The point is, if you people are reading it, please try to look for politically correct manipulation in your behavioral patterns and politically correct propaganda and so called mems around you and try to reject it even if it makes you to get labelled as impolite, agressive, or evil. Because this is a totalitarian - commie - way of controlling people and once detected around you you better get prepared. Not that people who encourage this way of thinking in us are all commies, they just want the same thing - that their TRUTH is a law and nobody dares to oposse it and most importantly discuss it and raise arguments against it.
EDIT Yeah I'm paranoid and simply scared shitless that commies would return. Labelled either as commies or anything else. Just some goddamned gang with one universal truth shooting others who won't agree and obey. I tell you people everything in Orwell's Animal Farm and 1984 is perfectly true. It's not a fable, it's about reality. There is not a single thing which is not realistic in that book. Well yeah smartasses animals do not talk but I'm talking the behavior, OK.

And that bastard Marx said that the commie revolution must win at the same time in the most powerfull industrial countries in the world to be succesfull, and I have a very strong feeling that you guys who spent the Cold war on the good side of the Iron curtain are begging to have the commie experience firsthand, so PLEASE learn from the very recent history and don't let these "good kind folks who have seen the Truth and know what is good for you and you will suffer if you dare not to obey" to win. Europe is fuckin going this way and I'm affraid that America is not much better.
