I am asking that indignation be a genuine reflection of one's moral balance, and not be used as a tactical cudgel on issues where one is actually ambivalent.

That's the same thing I ask for wars, if you abhor one then you should abhor all of them and reject all warmongers, but I'm always accused of "whataboutism".

More like if we're going to accept some amount of animal harm then potentially giving paraplegics a decent life should take priority over your happy meal.
