Not sure why this is such a controversial issue.  I know veterans who support the protest (i.e. they fought for the right for those to express themselves) and vets who think the whole thing is silly and disrespectful.  In the end it is under two minutes that this freedom to protest occurs.  Why all the fuss over two minutes?  Sigh!  Remember that the original intent of the protests were to bring attention to police violence and harassment on African Americans.  Which is a problem in this country that needs to be addressed - its intent was never to demean veterans who fought valiantly for the right to protest.
