You are absolutely correct- there is a huge difference....to you. I don't like it. I find it very offensive and degrading. The black kid could have shown he was better than the moron by ignoring him. I don't think the drawing on his t-shirt urged people to get married. Do you? Or, did it urge people to go to church? The message you are hung up on (pun unintentional. really) is the lynching. As abhorrent as the display was, it doesn't justify the assault.
(I wish there was a way to get inflection in text)
There is. Use < > and < / >, where instead of spaces, you insert b for bold; i for italics; s for strikethru; u for underline, then bracket what you want inflected with the first set of symbols in front of and the last set of symbols in back of.
Example (without any spaces between arrows): Well, we < b>don't< /b> rent pigs.
will appear as Well, we don't rent pigs.
