Your viewpoint will not, and should not, be welcome everywhere all of the time, no matter the specifics. This is normal and does not infringe upon your freedom to speak your mind online. If other people disagree, or even if platforms you don't control curtail you, that is fine: the internet, not a specific site, is the medium. You don't often get to publish your rebuttal to another author at the end of their book. Often you have to publish your own.

I feel like tech bros have forgotten this.
