Ok, I'll use the religious thing again. Do you not think that at least part of the intention of the Orange marches is to antagonise?
It's not that far fetched to think that some protests are designed to raise awareness and some are at least partially designed to stick it to people who disagree. In these instances, if they didn't want to "test" people, they would open it up to a general overarching gesture, rather than coerce people of different beliefs to play along or face fear of public backlash.
As for politically motivated, are we saying Back Lives Matter isn't politically motivated? I'd suggest whether or not you agree with what they stand for, or their means if doing, it is very much a politically motivated organisation.
The Premier League isn't, or shouldn't be. Instead, they promote inclusivity in the most natural and influential way possible. Genuine, organic, societal, grass roots acceptance and inclusivity through sport, which by its nature, should be inclusive and welcoming to people of all backgrounds, countries, races, religions, beliefs, through a common goal.
Unfortunately, society is full of people with very different views. Many of these people will not be reached by rainbow laces. And giving them any excuse to rebel or revolt is only going to do 1 thing. Antagonise.
You don't create unity by constantly ramming differences that most people dont care about on a day to day basis down everyones throats.
