in Holland we've seen environmental protests taking extreme forms while not being condemned as extreme. They're being discussed as "people who have concerns" while other groups aren't portrayed like that.
Also, a protester was invited to a popular mainstream talkshow and glued himself to the table (which was easily undone afterwards). Other protesting figures for other means, with a reasonable following, and never calling for arms (while being protrayed in msm to do just that), don't even get a seat on that "talkshow".
Also e.g. A protest organized by 'extinction rebellion' was able to seige a runway at an airport. imo, it's unthinkable for a random group to do that unless there's inside support. In my opionion millitary police would have intervened before they would be able to block the runway with those numbers.
