Both are self selected descriptors which could be reasonably objected to without denigrating or disrespecting the person specifically.
Removing the ability to engage in thoughtful conversation where parties disagree is a travesty.
I'll be blunt - as a strong atheist, I'm in full agreement with the moderator who posted this. I personally don't agree with his opinions on gender pronouns, but I think his point stands loud and clear: Respectful disagreement is no longer allowed.
I think that is especially poignant given the community he moderates almost certainly aligns with his views.
I believe many of the communities that press these gender issues are broken. Not because I care about "pronouns" but because when disagreement with the majority opinion is IN ITSELF considered an insult worthy of exclusion or derision, there is no longer any apparatus to allow honest discussion.
I have the same opinion of the most restrictive church communities. The mental process is the same - Disagreement is threatening, remove the threat through ostracism and social pressure instead of honest conversation. Fuck that. Fuck that on both sides.
