I completely disagree with this on basically all these points. Implicit bias only has shaky theoretical foundations and you don't have to be ashamed of being biased in the first place. Of course you have bias for friends and family. Principles and laws keep you from nepotism. But emotional ties are almost completely irrelevant here. The mafia isn't a real family.

These position are as non-judgemental as it gets. Gay marriage is a separate issue but many support it because of such positions.

Dominant society in liberal democracies impose almost no values on anything related to that and it is even part of the curriculum to educate people on different sexuality. But I think that problem is solved since a few generations. In many countries at least. Saying such positions would be judgemental is actually moving backwards again.
