Not at all. I neither think you should up your opsec nor avoid posting. I think you should be unabashed of what you have to say. I also think you should hear out others doing the same, generously and in good faith.
That tiny minority who harass and abuse queer people today? That used to be virtually everybody, all the time, everywhere you'd go.
The only reason queer rights are where they are today is because people weren't afraid to speak up, even when they had every right to be. When coming out meant admitting to criminal acts - proclaiming them in public, no less. Had they not put themselves out there - had they refused to speak to those that didn't already agree with them - this would be a much darker world, and your definition of 'unsafe' would be a lot more visceral.
People used to march, faces out in the open, in their small towns, for their rights, past neighbours who hated them. That's what 'unsafe for queer people' means. I'm just never going to be able to see 'people disagree with me online sometimes' as being in any way comparable.
