Come back and talk to me about guns after right-wingers have disbanded their silly "citizens' militias" in Virginia, all over reasonable gun restrictions that are 100% compliant with the Second Amendment.
Now, when you talk about Silicon Valley, you are talking about private companies that aren't bound by the First Amendment necessarily and may exercise control over their content. Same as ImgFlip, which has its own Terms of Service and reserves the right to delete any content that violates it.
Private companies have free speech rights, too -- corporations being people and all that -- and don't owe any one particular person or viewpoint a platform.
