Hmm....there's a lot going on there to unpack.
Agreed they are hypocrites, but I've never seen anyone say others have to respect any CSA flag more than or equal to the USA flag.
The irony is that the LWer haters of the South are fine with the Mexican flag over Six Flags of Texas, but forced them to take down the CSA flag. Another example of Northern hate, bigotry and hypocrisy. So they are in good company with the RW bigots who hate the Mexican flag.
The big difference is Mexico is an ally and part of the U.N. The confederates were a militant grouping with unsavory ideas. These groups pop up from time to time. My heritage is German and that swastika is in the same boat as the confederate flag. They are symbols made for museums and history books. Not standing on high as a symbol of respect. Waving that flag around African Americans is like plastering the symbol of the Japanese Kamikaze pilots over Pearl Harbor, or the symbols of the Taliban around ground zero.
