If someone has consistently bad ideas, you're not going to have a high opinion of their future ideas. If these are work ideas, they may also not be able to keep their job, which affects their livelihood. I don't know if we can get away with saying that taking away someone's job is not some kind of attack on their livelihood/self. So if you, the worker, are worried about having bad ideas that can affect your job, it isn't a stretch that the reaction to criticism can look like a reaction to a threat.
Now, criticizing hot takes and bad opinions on Twitter? Go for it, although that too can result in real consequences.
Part of who we are definitely involves the connections we make, and you can lose more shallow connections with bad ideas - good friends/deep connections tend to love you regardless. If you are trying to take your work seriously, but everyone ends up criticizing your ideas, it will also affect you.
