That is clearly stating that if you have an ideological disagreement hand in your resignation. Contradicting the claim he supports 'ideological inclusion and tolerance' in the preceding paragraph.
Nowhere in the text does the term 'hate speech' come up. He does make a reference to demeaning behaviour. That could easily mean ideological disagreement. If you find someones views on H1B visas demeaning they should hand in there resignation.
Also he states,
> we do not tolerate hateful attitudes on our team.
Again he states there is no tolerance for attitudes he may disagree with. Attitudes are simply ideas informed by ideology. What constitutes a hateful attitude could be any political disagreement of principle. Including voting for Trump.
This seems like a fairly pointed address to Trump voters that they should hand in there resignation.
