Do you think they should be doing something? If so, why? Why should political minorities get an uneven boost to their applications?

Side note: most people who apply to YC are probably not very public with their politics. Political minorities could do the same and not worry about repercussions for their beliefs.

Former partners such as Sam Altman and Peter Thiel have been fairly politically outspoken. Fairly uncommon in business before a decade ago in the US.

They accept entrepreneurs on merit.

That is debatable, they have been increasing cohort sizes considerably and using the many bets strategy of late.

There's only so much they can judge by in the small amount of interviewing they do. It's much like hiring

Is accepting entrepreneurs explicitly or exclusively on merit the official criteria?

Get rid of downvotes. They serve no purpose but to chill free expression.

Secondly, stop thinking of free speech as a right that protects us from the Government. The Government is rarely the issue in the US. The free speech ethos should be something in my head that protects you from illiberal outbursts or actions on my part.

Oops, I read the question to be asking what YC should be doing to address political diversity...

I'll put that up next.
