Based on reading your comments for several years, I presume you are very much in favor of protecting employees from various kinds of discrimination(as you should!). Advocating firing Thiel seems to be counter to that.

- If YC severed ties w/ Thiel, as people are recommending, should YC also divest itself of companies with founders who support Trump?

- Should YC-invested companies fire employees who support Trump?

- Imagine the shitstorm if a right-leaning YC founder fired an employee for working in the HRC or Stein campaign. The no-discrimination at any cost crowd is going to howl with rage the first time "their" person gets fired by "the other" camp, solely for political affiliation.

- Ok, we could pass some employment law: "firing employees over political beliefs is not OK, unless it's an existential threat". Who gets to decide what is an existential threat?

This is a very dangerous weapon, and your eagerness to use it now makes me think you haven't considered what will happen when it's used against your political tribe.
