I was specifically referring to the deflection of "If I was Muslim or Jewish, I wouldn't be under scrutiny for splitting my vote between my publicly stated position and my personal religious viewpoint".
Whilst I think abstaining on the vote is a bit cowardly, I am an atheist who believes politicians should be secular (and my old MP voted consistently catholic, which was always an issue when otherwise he was spot on with everything, at least till his sad demise), and I can understand the reasoning why. Doesn't mean it's not a perfectly valid weak point to be targeted for if you claim the position of championing equal rights for gay people.
It is complete hyperbole to be attacked as 'not liking gays' I admit. But I think responding with What-about-ism and playing into the divisive rhetoric that claims Christians are some kind of persecuted group is a significant low. It's also inaccurate (A Muslim MP would certainly face scrutiny), and though it might be relatively harmless this kind of ****shit has been shaping politics for some time and it's not winning me over.
