This is really not a gotcha.
Unless you go through each one in turn and find out

Particularly since at the moment equalities has been warped to the point of basically meaning TQ+. If these equality votes were to do with things that damaged or harmed the eight other groups then an MP might well have had reasons not to vote. The whole black and white, 'if you don't vote like one of Pavlov's dogs every time someone holds up something saying LGBT+ or Equalities you're evil' thing is beyond silly.
Baroness Nicholson is constantly whined about for voting against gay marriage. ^Many gay and lesbian people did not agree with the vote, as it stood, with the wording, for gay marriage'. That doesn't make them homophobic or evil.
