David, posting quotes, without context or explanation, is not the same thing as pointing out logical fallacies. There was a discussion in which ABC10 was posting obnoxious stuff to bait some of the people here, and several of them responded by making tendentious statements or attacking Republicans or conservatives in general (actually some of this happened in subtler form even prior to ABC10's posts). To varying degrees, the posters you quoted responded in kind.
As to the quotes you gave, I don't think any were irrelevant or fallacious in context. They wouldn't ordinarily be relevant in a thread such as this, but the thread was going off the rails a bit, and they were apt at the time.
For example, I think Caper was making a fair point that racism is deeply embedded within human nature. We can only make it socially unacceptable to express it publicly (or illegal in some cases), but it is impossible to eliminate it. As he indicated several posts later, he in no way meant this as a justification for Sterling's blatant racism, nor did he mean for it to be an absolute statement. So there was no false equivalence, nor was it fallacious in any other regard. That post and Applecorp's posts (including those sent to AAH) I saw as mostly in response to an implication that Sterling's racist rant was proof that we don't live in a post-racial society and that therefore those who want to move beyond race are disingenuous or wrong.
I don't remember the context of ravdin's quote precisely, but there sure was a lot of conservative-bashing going on. I think it was fair to point out that there is actually quite a bit of racism within the Democratic Party, and arguably the whole framework of affirmative action race-sensitive policies which they advocate is racist. The way conservative blacks are vilified is particularly appalling to me.
As for my writings, you still haven't explained how they were logically flawed. Just because you don't agree with something doesn't mean it is fallacious.
