Sometimes no comment is needed to show how radical the Left actually is. One key thing to mention is the importance of listening to different opinions and arguments. This is something the Left never does which explains why they get so shocked or offended when they hear something which conflicts with their worldview.
John Stewart Mill said it perfectly in his 1859 essay titled ‘On Liberty’:
Complete liberty of contradicting and disproving our opinion is the very condition which justifies us in assuming its truth for purposes of action; and on no other terms can a being with human faculties have any rational assurance of being right.
Don’t just assume your worldview is the correct one. Validate it by opening yourself to differing opinions.
