Moderators banning/censoring people arent oppressors violating your rights; they are customer service representatives curating a space for their intended customers. All this to say, I see you Karen.
If you trust this person to tell you, and everybody else here, how to speak, then either your speech is worthless to you or this conversation is worthless to you.
I don't think there is much swaying of opinion in online conversations so most conversations is just bluster or time sinks. If anything of value is ever being discussed it is almost certain that astroturfers have infiltrated the conversation and diffused any real action that may have come of it.
Think of reddit. Think of the top 2-3 comments. There are a mountain of comments under those that just fade into obscurity. Their could be someone on reddit posting the "meaning of everything" on every post that hits r/all and it's been virtually censored by just the sheer amount of garbage spam that thoses post will receive. Gaurenteed the posts with the most engagement have been artificially boosted.
I do this constantly and get challenged a lot. The people challenging my ideas and thoughts arent trying to convince me of anything. They are trying to wear me down, that's the strategy. If that's what we are up against then nothing good will ever come out of these spaces.
