Advice of the day...
See a meme you don't agree with or like? Just move on. You might try it some time!
'We The People' will sort it out. Freedom involves our right to hear and see information. Censorship is not good for America. Remember, liberals generally react emotionally (set fires, destroy cities, damage Teslas, etc.) ...conservatives react cerebrally (you know, the old 'facts over feelings' which leads us to the truth obtained not through violence).
