Using the crude language is not typical. However, there are a block of voters who will NEVER vote for a woman. They are not shy about telling you so either, trust me. Same issue for racial voters when they go to the ballot box, black or white. If their candidate is the same race as the voter that candidate could have raped their grandmother on live TV and the voter would still justify and vote for them.
It's still a more or less free country. Would you compel them by force to vote your way? Same with the racial voters. You may condemn them as ignorant ... they would likely say the same of you. You just have to accept their existence.
