Your entire argument here is basing that people have a right to express an opinion on a social media site which is categorically false. They have the right to express an opinion, sure, as does the guy with the sticker. He does not have a right to a digital megaphone with which to do that: that is granted to him by a platform like Facebook.

Nah, my argument is based on:

"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."

Nowhere is mention of 'amplitude' of speech.

If Facebook et al want to restrict what their users say then good on them, they are a private entity and can do whatever they want. Destroying these platforms because they allow speech you don't agree with is not the job of government.
