Yes, leftists are really strong in censorship. Some time ago I was a leftist, because I didn't really understand what I was supporting (like many leftists actually) and at that time I wouldn't mind censoring the right-wing posts. Which was just a proof how wrong I was.
But now that I know the true leftists agenda, and how harmful they are, I know that this modern stealth censorsip should be punishable by government. You don't have to worry about Russians interfering with elections. Worry about Google.
I've for example found it impossible to access certain political websites using Google. They would be listed, just like all other links, but when you click them Google would say: "The site is unavailable". Or would take me to another site. I really thought that site was unavailable. But I was intelligent enough to type in (letter by letter, because copy/paste didn't work either) the URL into my browser's address bar. And guess what - The site was fully operational.
Now, that's the level of censorship that eve North Korea would be proud of. It's the African dictatorship level of hiding information. That must be illegal. Google should be punished for unlawful censorship.
