Nah, I think that you've still got to accept and engage with people who are intolerant of others--again, you yourself are a member of that group.

It's not usually a big deal if you are interacting in a strictly professional capacity: if they let their bigotry get in the way of good business and engineering and teamwork, you can drop them on those merits alone irrespective of their reasons for being subpar engineers or businessmen.
