I love Fluther and the interaction with different people, but why the flame game?

I find people so intelligent on Fluther and interesting and I love it. But when people stop disagreeing on issues and start what I call the flame game I get uncomfortable. Why the flame game, and name calling? Is it because one can do it incognito or that one has a venue to let it all out due to their own problems, or…...? This old gal just doesn’t get it!
