Why do leftists always seem to make excuses for this guy? Yeah he has been part of some great work, especially with Snowden and Bolsonaro, but he has some real chud tier beliefs. To me he seems like your bog standard libertarian, meaning he has no conception of societal power dynamics and his concept of freedom is limited to the level of the individual.
No you have answered your own question, "Why do people critically support Glenn?" I am asking "Why are there so many people who seem to uncritically support him?"
Again, the answer is still the same. Not sure what's confusing you but I don't think I can help.
