I just don't involve myself in childish drama. Somebody wants to be an bellybutton they'll get bored eventually and leave. Never understood the dynamic of drama on a forum. Don't like someone? Don't read their posts, block them, and move on.
I'm pretty much the same guy in real life I am here. I always want to be pleasant and am always willing to listen, politely, to a view that opposes my own. In doing so I've learned much.
I'm much more concerned with being polite and respectful than I am with being 'right'. I can always think 'well that's your opinion but I disagree and your argument hasn't swayed me' and end the conversation. Why pick battles especially online?
