For whatever reason, YC has chosen to stay silent while one of its partners pours resources into a candidacy outside the bounds of normal political discourse in the US. This silence is very weird, especially considering the individual partners' alarmist comments about Trump.
I don't think YC became poisoned with Thiel's views the moment he expressed them. They were poisoned by his views when they chose not to react in any way, and maintain their silence. I wonder what women, Muslims, veterans, etc. in this thread feel about the matter.
To the point that Thiel doesn't completely endorse his candidate, I believe that argument is substantially weakened by his 1.25M donation coming after multiple accusations of sexual assault. Clearly Thiel is comfy enough in his support to disregard this, and the parade of horrors that preceded it.
I accept that I may be starting to sound a bit nasty. I consider what is happening a display of spinelessness, and the arguments being marshaled in its defense disingenuous. It makes me angry.
