That wasn't its original intention. I 100% back McClean's right to choice. I'd imagine he would never speak out against a player wearing the emblem in question - as it's a matter of choice. Should FIFA insist on removing Crescent Moons or Crosses from National jerseys?
There were players from both sides of the sectarian divide playing for Northern Ireland in Euro 2016. I wish they could find an anthem that represents all of Northern Ireland's citizens rather than the one they use. But the players involved made their choice to play for Northern Ireland just as McClean made his choice not to.
Where I do see an issue is that it seams every presenter, pundit, newscaster, reporter, etc on any British television show seems compelled to wear a poppy in the run up to Nov 11th.
