Oddly enough, what really makes me roll my eyes on the pro-Trump people who made the tweets pop out is that in the end, all they did was shake one guy and ruin a movie production...but not really much else.
They could have done this to bring someone with ties to politics down. To REALLY push their agenda. What did firing Gunn accomplish?
Shake the industry? Not really, Disney is not gonna be shaken from this since, as you said, it's all business to them.
Shake the MCU? Not either, cause even without GoTG the rest of the movies will continue selling.
Show how their side and view is superior? Not really since Gunn has ZERO political power or sway. Might as well had just made someone quit Tumblr and they'd have had the exact same effect politically.
How about show that the other side is hypocritical, putting the ones who did this on a higher horse? Also pointless, since controversy like this will eventually die out and vanish the next time the right or left do something stupid on public.
My point it, that the thing I hate about this is that it was POINTLESS. Nobody won anything out of this other than making some people mad, and which later will forget about it next MCU movie comes out.
