Ahh - predictibly, now I'm both a racist and a sexist (won't be long until I'm a racist, bigot, homophobe, xenophobe, etc).  I haven't read about the Pence situation because I don't really care about sports or about the Trump administration.  But if he is acting like a snowflake being offended then yes.  If he is "protesting" their "protest" - maybe not.  The administration does very little I agree with.

Some people take offense to almost anything - that doesn't make it offensive.  If no intent was meant then education is the answer - not public execution.  Further, sometimes it is the offended one that needs to be educated.  Just as you demand I should have an open mind - sometimes the offended needs to have an open mind instead of excoriating the offender on media/social media.
