Are white people that aren't racist, but not comfortable voting for a minority welcome in the party?

33. Tell your friend this:

A. If he has a legitimate reason for not being comfortable voting for a candidate from a minority, he should enlighten us all with what that reason is. I would think his being welcome or not hinges on the coherency of such a reason.

B. If his reason for not being comfortable voting for a candidate from a minority is ridiculous, then he is probably better off keeping his mouth shut, as Democrats don't believe that there is any reason that is legitimate. The Republicans seem like their better alternative. What do we have to offer them?

C. This friend is only "uncomfortable," according to the OP, not emphatically opposed, to voting for a minority. Ergo, logically, they can handle a mild degree of discomfort. If the nominee is a from minority, then a majority of those who voted in the primary voted for that nominee. If THAT makes them uncomfortable, then they should move to Wyoming, or some such state where the likelihood of such an "uncomfortable" Democratic candidate is remote.

I don't think "these people" have any business telling the rest of us whom we "need to nominate." The majority nominates whoever it wants to nominate. If this friend is white and thinks they are a better candidate, they should by all means file to run.
