The First Amendment of the United States Constitution reads thus:
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
Notice the very first phrase: Congress shall make no law. This does not apply to private property, private gatherings, or private media outlets. In other words, private citizens are not obligated to tolerate your racism and stupidity!
If a furry convention, a privately-funded gathering on private hotel property, decides they don't want a fursuit covered in hate symbols on their grounds, that is their right.
If a media outlet decides not to give you a voice because you like spewing anti-semitic conspiracy theories that is their right.
If the company you work for fires you because you're making Facebook posts about how homosexuality should be a capital offense, that is their right.
Like it or not, free speech does not mean speech free of consequences, and it does not mean you can blast your ignorance in somebody else's private space. You have no right to demand a platform for your ideas from someone who doesn't want to give you that platform, because when you do, you're demanding special rights.
You can rant on about how the SJWs and political correctness is ruining this country, but no matter who you elect, they can't change anything because there is a little thing called free association. Your "politically incorrect" candidate won't make it OK for you to spew hate on your favorite website because there is no legal precedent for forcing private interests to tolerate your stupidity.
