Well obviously if I have heard plenty of Republicans and/or conservatives denounce the use of the N word and all other fowl language and you haven't then the only conclusion I can draw is you haven't looked.
I don't think the majority of Democrat ever looks. Especially here on ImgFlip. There are so many who think that all conservatives are white supremacists and members of the KKK and the neo-nazis. Antifa went around calling everyone who was not them, "fascists", and they haven't the slightest clue what a fascist is. They think fascism and racism are the same thing.
Will you denounce Joe Biden's use of that word and all of his other racist comments? And before you play the "Trump's worse", let me first inform you that of all of the things Trump has said, what he said one time about illegal aliens, was the ONLY racist thing I have heard him say. I have no idea what he says in his private life because I am just not devoted enough to him to dig into his private life. I'll leave the Democrats for that. They are searching anything that can possibly find to crucify him. They weren't able to make any of the of their fabrications stick.
The biggest fear Democrats have is that Trump will be able to run again in 2024 and they know that Biden doesn't have a snowball's chance after the colossal failure of a president he is. Not even the "I hate Trump so much that I will vote for one of the worst presidents ever" vote will hold Biden over. They'll have to try to recreate the 2020 voter fraud, only this time everyone will be watching and they won't be able to get away with it.
I personally would like DeSantis or the Indian guy whose name I forget have a chance. I think either of them would make a far better president than Trump. Dems fear DeSantis for that very reason. And that is why they have been going out of their way to attack him every change they can get.
