joining the fediverse to bitch about reddit is the same as going on a date, and spending the whole night talking about your ex

So it’s okay for you to bitch and moan about stuff you don’t like, but others aren’t allowed to be upset about Reddit?

I think you may have been letting your frustrations guide your words. End of the day, we all (including you) are allowed to express your frustrations on anything, but you being frustrated with their frustration is only going to spiral out of control. Try something else like going to those threads explicitly and derailing the conversation towards something more positive and constructive.
