I think what Dynamo is inferring is, don't put all left wing stereotypes on people whom you see as leftists. If you're talking to Dynamo, then speak to Dynamo and only hold him to account of things he has said, not an entire ideal/party that he/she might not be apart of.
That's all well and good. I'm not generalizing on purpose and if I'm not mistaken, I've owned up immediately every time I do it. What I'm not gonna do is swing by the thread, see a post about "No, the people I see who did the milk meme totally WERE racists though," and pretend that the other 23 hours of my day didn't happen and I don't already know better.
