I haven’t examined all of the evidence, but on the surface it does appear that Trump might have at least indirectly been involved in provoking the riot. If true, it was 100% wrong of him to do so, even if the election was stolen - and I’m not totally convinced it wasn’t. I saw clear irregularities that have never been explained in the voting data from cities like Philadelphia, Detroit and Milwaukee. If true, that would be 100% wrong as well.
That said, why must it be like choosing the least worst candidate? Many liberals really didn’t want Biden, but they’d take him over Trump. Many conservatives didn’t really want Trump, but they’d take him over Biden. Both candidates actually lean moderate, and neither uphold their party’s ideals in many ways (although Biden now seems to just be in “where do I sign” mode, and agrees to anything his party wants). There plenty not to like on both sides — I don’t see how people can have so much zeal for either side.
