Yes - and a wise choice of friend is somebody with opinions different yours and good reasoning behind their thinking.
Absolutely good advice here. Ideology alone is a poor way to choose friends. Some of my best friends are devout Christians but I can't think of any other anarchists I'd really want to spend time with. Most anarchists I've met and can think of are humourless dicks. Chomsky anyone? They have plenty of good solutions for a better, more just world but it's the redneck BBQs I'd rather be at.
