I think everyone and anyone who criticizes capitalism for any reason whatsoever should be sent to live to a 3rd world country for one year
Why does the criticism of capitalism bother you?
I won't allow people to talk shit about capitalism, it's not fair for my capitalist friends
You should not tell people that they should not criticize capitalism. Instead, learn to respect their opinion even if it's different than yours.
What if they don't agree with my opinion?
It's normal and fine for people to disagree with each other. Everyone has their own opinion and you have to learn to respect the opinion of others, just as you want people to respect your opinion.
