That's because it does. Republicans have constantly done everything they can to keep people dumb. They've time and time again voted against anything that will improve education or bring it to a larger group of people. This is intentional too. The easiest way to control someone is by keeping them uneducated. If they don't develop critical thinking skills or just learn history then they can't call you out on your bullshit. Hence why our education in this country is atrocious.
I agree with a lot of your points, but I also think you are dismissing conversation and opinions from people who may be republican and conservative but also have more informed and benevolent opinions and are willing to have educated discussion about that. Here's what I put on the last page.
"Ugh, I feel for all of the more conservative folks whose ability to have rational and productive conversation is limited by this vocal minority or racists and bigots with an "all or nothing" mentality.
Those of us who may be a little more liberal skewed are in an environment where a lot of our opinions and validated and challenged respectfully, whereas people on the conservative front are being represented by clowns like JonTron and Trump.
If anyone's speech is being limited it's the level-headed conservatives... and the ones limited it aren't the "oversensitive PC" folks... it's people like JT who are creating such strong, negative associations. "
Not tryna come after you, but I just don't want the racists and extremists to inhibit good conversations from both sides.
