Call me what you want but I know for a fact the tech sector is filled with leftists who will do what they can and use the tools at their disposal to silence those they disagree with
If the tech sector is trying to silence views of the American right, it's beyond obvious that they have not succeeded.

We remain a country with a broad spectrum of political opinion even within the conservative and libertarian ranges, and certainly on the left as well. I would say the last thing the tech sector wants is censorship. They are about making a buck the same as the rest of industry, so hearing current and potential customers is important.
As far as expression of opinion on the net goes: as long as a site makes its guidelines clear then moderation along those guidelines should be expected. Anyone who posts provocatively enough and often enough at the margins should not be surprised to find some of his subsequent and similar material deleted.
Maybe to get somewhere with "censorship" arguments one has to ask whether far right ideas today are being drowned out of our national conversations. I certainly don't think that's the case. From the President on down to members of this very forum, there are vibrant examples of right-leaning speech informing us that not everyone leans left and that other views not only exist but are flourishing in some quarters, including parts of the White House, Congress, mainstream media, colleges and universities, right on down to town council and school board meetings.
All our sound and fury and still we stand equal in eyes of the law. I guess that can be exasperating or exhilarating depending in part on one’s politics, not just one’s skin color or other external attributes.
Just because one has not managed to sell in some idea doesn't mean that its advocates are not being heard. It can mean the ideas are not being found attractive. The Republican Party is what currently shelters the far right view even though it does not always endorse it explicitly. It is, however, the party of the political majority in the White House and Congress at the moment. Maybe people on the extreme right who are crying "censorship!" need to ask Paul Ryan and Mitch McConnell why they don't offer more of a bully pulpit for the far right. After all, it seems rather unreasonable to ask the left to supply it. We are out of favor and relatively powerless, at least until the midterm ballots are counted in November.
In the meantime Twitter doesn't seem to censor left or right wing views either, as as long as they're couched in terms that meet their guidelines. Left and right could both be more moderate in our political discourse today. What some drunk engineer at Twitter said is on him. What we all need to do is ask what we expect of a social media site. After all, it should be a pleasant place to visit or why go there? So there must be some moderation, as we can see just by looking around that we're not big on self-restraint in the USA at least. It's probably very hard to write algorithms to help automate the moderation effort. If we don't like being moderated out of any discussion, then applying some moderation before we post would be the smartest thing to do. Maybe Twitter should pitch that idea when we log in!
