How is calling out people for highjacking discussions that are remotely about their personal convictions to preach about those convictions 'mean'? If anything, this site should police such behavior more - what we have now is half of the posts arguing a straw man because they see a keyword in the title and feel they need to defend their ideological positions. The OP is about how vegetarianism won't lead to sustainable food supply - and the GP answers 'you should become vegetarian because poor animals'. Fine, but in the context of this threat pure noise. Look, I'm not saying I can always restrain myself to stay on topic in every post I type; I'd be happy to have those posts summarily deleted too if that meant the signal to noise ratio in the comments would increase.
