I'm sorry to hear that has been your experience within this community.

People who think differently or don't know are treated as if they are fools and hostility is their reward.

I have seen this and been on the receiving end of it as well. It's often just a handful of loud minority (I can think of about 5 to 10 accounts who do this often). It's truly unfortunate, but I'm hopeful communities can help with that so people can manage them and exclude people who do not follow the guidelines of that community.
