I'd rather no one lost their jobs for opinions, good or bad. It's all part of conversation and idea exchange.
I think the main problem of late is the wilful bad faith interpretation of utterances by others, i.e. I'm going to take the most spiteful uncharitable interpretation of what you said and throw it out onto social media to see who piles on. That kind of toxic poison is apparent on both ends of the political spectrum, and could do with being fired into the sun.
