Look, if someone blocks you it's likely because you're being annoying or an asshole, it's not some revelation of a deep flaw in THEIR character or a reflection of their inability to communicate (they clearly communicated a hard boundary via their actions).
In my case, I can totally get why someone might want to block me, sometimes I'm a lot for me too! Sure it's disappointing when it's someone I respect or who's thoughts I value but that's still on me and up to me to reflect on my own actions. Sure maybe it's a combo of me and the other person having a bad day, maybe I didn't intend to be annoying or overly familiar but clearly I was being annoying in that moment. Nobody owes me their attention nor do I have a right to their thoughts on social media. So, please, when you get blocked stop trying to take it to the court of public appeals and trying to turn other people against that person. They're blocking you does not make them a danger to other people (and may indicate that you are lacking in self awareness and have a tendency to avoid responsibility for one's own words and actions).
