You can hold whatever selfish, "fuck you, got mine- try being born into better circumstances next time, losers!" opinion you want. Your free speech doesn't mean everyone else has to listen intently and earnestly and keep themselves from thinking you're being an a-hole for holding the opinions you do. It also doesn't mean some private social media outlets can't tell you to piss off for posting them in a forum about metal music. There are plenty of places online where you can post such an opinion and be back-slapped and congratulated; lamenting that one takes a preemptive stance against opinions you hold is pretty tender for one who takes such a cold-hearted stance against refugees.
