the potential customers that would already point their finger at you screaming "shame" if they saw you do business with people they dislike? Good riddance.
Even if you go by voting numbers in the only election he actually won (and even that wasn't by popular vote), it WAS closer to ⅓, and that was SEVEN YEARS AGO. I'd wager quite a few who called themself a supporter back then have changed their minds since. They're just not speaking up about it, and so the perception is skewed.
Well... it's worth noting that (IIRC) a record number of people voted in the 2020 election, overall and for each major-party candidate. Are those who chose to vote for Trump not to be counted among "Trump supporters"? It was approximately (but decidedly not quite) half of voters.
Yes, but I was highlighting the disparity between "active voters" and "Americans in general", and between them and now. Saying half of the country supports Trump simply isn't factually true.
Now, whether people who don't vote should even be part of the conversation is another debate, of course.
