In "Liberal Land", nothing means what YOU think it means. The only acceptable definition or interpretation of anything - hats, jackets, flags, words, pride - are those put forth by liberals. In their mindset, only their views count and anyone who disagrees with them or persists in defining things for themselves is a "racist" or an all-around terrible person. Liberalism is tyranny.
Of course it's not a modern-equivalent of a Klan hood. MAGA and all hats, T-Shirts, banners, etc. featuring it, represent the ideals of a united American population - all races, religions, cultures and creeds working together to make our nation strong, safe and stable for everyone. Clearly, anyone who opposes these things is behaving like the Klan, "MAGA" is the opposite. That being said, a BLM flag with it's attendant Black Supremacy, is akin to a Nazi swastika flag. That is a far better comparison than the faulty one you chose.
