I read the whole thread, and it wasn't nearly as bad as I thought. I thought it was going to be full of bashing and hating.
So what can I say that hasn't been said....
Thinkers have feelings too. Saying thinkers aren't emotional is like saying feelers don't think. Some thinkers are less emotional. Some are very emotional, but you wouldn't know it because they don't show it. Some thinkers are trouble controling emotions and may actually seem more emotional than feelers. Or some combination. I often have hidden mood swings because my emotions were too strong (inappropriate or over reacting) and I was embaressed by them.
Generally I try to start out with a positive, or at least a neutral opinion toward people. If I react poorly, it is generally a reaction to the way they have treated me.
I identify to a large degree with how some thinkers may have been harassed by a feeler which they over generalize into a general dislike of all feelers. With me it wasn't just one "bad feeler" but a many, many feelers who have given me a hard time, so the tendancy to generalize seems a bit more reasonable. I don't know if there are lots of bad feelers out there or if I just got really unlucky to run into so many. Still I try not to hold it against feelers in general.
I was verbally bullied in school quite a bit and it was pretty traumatic. I suppose not all of this is F v. T, being introverted and N probably didn't help. Not having good social skills is generally attributed to T (or more correctly low F) and that was probably the biggest factor.
I have had issues with people whose have strong values I don't agree with. I will not react hostilely to someone because their values are different than mine, but I have ran into many feelers who will harass you, reject you as a friend or look down on you because you don't share their values. I lost a friend, some one who I invited over to my house many times, becuase she felt my D&D character was behaving unethically.
There is the F with status quo values, who reacts badly because my values are not the same as the statue quo, popular culture, etc. A common variation of that is the "what would people think" feeler. Often this is in reaction to some trivial transgression like wearing the wrong color shoes. Then there is the idealist, such as the vegan who says "people who eat meat are evil" [not saying all vegans do this] or the fundamentalist who says "people who don't follow my God are going to hell."
Also, I rarely display my emotions and it really bothers me when people try to pressure me to or look down on me because of it. It gets to me when people act like I am a heartless

because I don't

when they tell me their dog died or their kid is in the hospital. I am really bad at expressing sympathy but that doesn't mean I don't have care.
