I totally agree with you...freedom of speech tends to become a luxury nowadays...I firmly believe that through healthy debate, new ideas are born and we evolve in general
I am a strongly believer of the quote that saying :
"I may not agree with your opinion but I will defend to the end your right to be able to express it"
It is a luxury indeed. And I'm even more amazed by platforms that claim to be independent and free, but in fact forbid you to say a single bad word against the status quo.
I believe too that debate is the most useful and healthy thing, a tool and an ability that has been given to us as human beings, which should always be used in the best way. If we don't use it, what are we more than animals/beasts?
