I am fully aware that those barriers exist. I am arguing (in other comments I am more explicit) about fighting against barriers, not a particular barrier.

I am also a foreigner in another country, and despite being a privileged person from many point of views (I could attend public university despite my family being poor), I have experienced some form of discrimination myself, so please don’t make assumption about other people’s. I am not blind to those kind of barriers, I simply have different opinions on the actions to take to improve the overall situation, with the goal of removing the concept of barrier, not any particular one (if that makes sense).
