Those who don't want 'real life'/politics clashing with their hobby are those who have the privilege of being able to take part in that hobby without being affected by the issues that people have been raising.
I don't think you got flamed. People responded to you, and they disagreed with what you had said. When you're wrong about things a lot, that's going to happen.
Could you clarify what you mean by 'a man is a man and a woman is a woman'. I'm not sure I want to know the answer, but statements like that sound eerily like things that people with terrible views say.
Back on topic: Kelf, I'm glad you've made this into a more positive thing. The gamergate comments and the link to that article both concerned me, as I was glad to have met you at euros and didn't want to discover that you're pro-gamergate or alt-right or anything like that. Thanks for explaining better. You do have a habit of saying things online that come across as provocative/offensive and, while it would be better if you could avoid that, if you do say something that elicits a widespread negative reaction, it's good to take the time to understand why people responded negatively to a thing you said. As you seem to have realised, if nearly everyone in a group of people thinks that what you said was a bad thing, it's more likely that you said a bad thing and less likely that they are ganging up on you.
Keep it positive, Kelf. And probably best not bring up topics if you're unaware of their history.
