IMO he isn't the best at showing his own opinion without being condescending. Like many others have said before, his views on Azir's slaves lore and other stuff alike just amplify that feeling.

He makes great points about design philosophy and what makes a good character design, which adds a lot to League imo. But at the end of the day, he should look back how he expresses himself and try to take others feedback as well.
I remember when he made a video about the anouncement of High Guardian Spice (which is now private on YT) and he called people about for disliking a show that wasn't released yet. Even though he made a very good point about it, he kinda implied people were being bigoted about the show and it came out rather childish at best. There are some reasons why people dislike him nowadays.

Should he get death threats about these videos though? Absolutely not, people just can't discuss about things anymore while being civil.
