I didn't say "too political" I said "too much of a hot potato". Basically I did not care for the original warnings poster stating not just that she would warn for abortion but that she had difficulties with its being written at all*.

Using warnings, I can see the logic, as stated by you above, though I also have qualms about how the warning would be worded, since it's one where there are triggers in both ways and where the warning should reflect that.

That is, people who have had abortions might well want to be warned about fics which consisted on thinly disguised sermons on how women who did this were assuredly going to hell. After all, I couldn't even go about my lawful business in entering a Seattle hotel last year without having to fight my way past a bunch of protestors with truly revolting visual aids, whose entire aim and object was to trigger as many people as possible, and I'm sure the fic equivalent of that deserves a warning if anything does.

My unease, therefore, wasn't about the idea of warnings for abortion per se, but the way in which the poster said that even if the canon source contained abortion she would not write it (*which, in a warnings policy which is explicitly set out to be borrowed, comes over less as a statement of personal actions but more as a "And even in some cases warnings aren't enough and I shall think you're a Very Bad Person if you even dream of touching these topics").
