The fact that Republican leaders have to even "urge party members to avoid racist and sexist attacks against Harris" in the first place should tell you all you need to know about how deep the bigotry is embedded in the Republican party.
Notice how Democrats don't have to, for example, tell their party members not to use racial slurs when campaigning against Tim Scott.
someone's a cranky old white man. wonder why everyone hates you, maybe you should dig into those deep pockets of yours and use some of that objectivity you're so fond of
If you had some objectivity you wouldn't have made yourself look silly jumping to wildly inaccurate conclusions about who you're talking to just because they suggested you be a little less racist and sexist towards people.
