seriously
let me break this down
>america fascist
really stupid, every nation including communist ones is fascist if that's your criteria. There hasn't been, and still isn't a nation quite as obsessed with liberty or liberalism than america.
>chemical weapons
YOU MEAN THAT SHIT THEY USE TO DISPERSE CROWDS INCLUDING THEIR OWN CITIZENS

>civilians
WHO WERE CHARGING THE US BOARDER TO ENTER ILLEGALLY

So what you're telling me, in unbiased terms is
US representatives unload tear gas to non-lethally disperse a crowd; attempting to enter the country without it's permission by force.
WOW
so fascist
Just rev up those ovens my dude

And being a person that lives on the country that got hit by the tear gas i can tell you, our people cheered at this, these migrants are making a mess here and affecting the people that need to cross legally to the USA.
