While you (and others) may believe conservatives are fundamentally 'bad' people and Silicon Valley (and the world) would simply be a better place without them, this is short-sighted (amongst other things).
Conservatives and liberals obviously see the world differently. One ways that manifests itself is that conservatives are typically more detail oriented and liberals are typically more creative. As Dr. Jordan B Peterson phrases it: "Each of those different temperamental types needs the other type so economically speaking, for example, we need liberals to start businesses, and we need conservatives to run them." https://vid.me/3Dik
Seems like Silicon Valley would very much suffer in the long term from a lack of multiple viewpoints. Is this not what the call for diversity aims to achieve?
We should be careful not to dehumanize our political opponents. That way lies violence.
I would imagine the amount of Conservatives that are not willing to discuss their views publicly is pretty large.
While not a Conservative, I was unable to discuss what many would view as centrists ideals, without being berated about how I was this or that. Political extremism is a thing on both sides.
I'm a leftist(demsoc), but frankly if they're willing to work without hostility toward their coworkers I am not particularly concerned with their positions on taxes or whatever. In fact I view the idea that someone can be fired because of their political position as a threat to labor rights. Excluding of course any positions relating to protected classes such as gender, age, national origin, disability. If you think your coworker shouldn't have the right to be there and are creating a hostile environment, you're the one that has to go not them. Otherwise yeah I have no problem and have happily worked with those who I believe are fundamentally eroding our democracy :V.
Both sides of that are actually debatable - there are arguments to be made for biological determinism, and thus that your political views are NOT a choice, and some of the people arguing in favor of 100+ genders or transracialism really seem to act like gender and race can be a choice...
I don't know if I'm moving the goal post here, but as far as I know POC and women aren't per definition known for doing the opposite of what made SV successful (-> not conserving old stuff, but trying new and innovative things)
I mean if there aren't any conservatives now, it means it got big without them. Why should it add such people? This would only lead to its demise.
