First, I'm gonna say a few things more than you asked. Do not generalize. Most Republicans do NOT support the KKK nor PB. In fact, it was YOUR party that promoted the KKK in its 1924 national convention & fought to avoid slavery being abolished. Liberals are like, "Do YoU rEaLlY tHiNk TrUmP sUpPoRtErS aRe ViCtiMs?!" You know what I say? Hell, yeah! We're treated like monsters! We get attacked much more than do Liberals get attacked from us! Some old lady carrying a Trump flag got attacked by some crazy ass Antifa members! Those are the same people who burn the American flag! Not just physically are we attacked, but we've been continuously verbally attacked & cancelled for being "racist" with no evidence. I'm tired of people automatically assuming I'm some racist bigot. I don't have a problem with minorities; I have a problem with Liberals manipulating them to their own advantage & also the fact that BLM is extremely aggressive & violent. MLK, a Republican, did it right by using peace. BLM, on the other hand, is a violent movement that has caused billions of dollars in property damage. While their cause is good, they have corrupted the civil rights movement. Now, to answer your question, I'll say a few things. The PB & KKK are AUTHORITARIAN, NOT REPUBLICAN. They may be on the RIGHT of the political spectrum, but the FAR-RIGHT, which, despite what you may believe, is completely different. & if you didn't know, BIDEN is the one who eulogized Robert Byrd, asserting that he was the Grand Wizard of the Ku Klux Klan.

It was the same Liberals who said that PB is racist despite the fact that the founder is a Cuban black & the group is very diverse. Yeah, f**k them, but they're anything but racist. The KKK, however, is very racist, so f**k them even more.
