Most condoms = not vegan
The pill is tested on animals, and purchase of it gives profit to pharmaceutical industries who continue to abuse animals in this way, so it seems like minus six and minus half-a-dozen, to me, from a veganly perspective.
I wouldn't dose myself up on hormones, especially not the Super-HardcorePill(tm) *use only in critical situations* , anyway, but if the two options would be (A) people have lots of penetrative vagina-themed sex, and produce lots of babies or (B) people have lots of penetrative vagina-themed sex, and do lots of weird stuff with hormones to prevent pregnancy, thus not producing lots of children. ... then i would say that option B is preferrable to option A..... but that all the same, it's the best of a bad lot.
If i were going to go in for that particular brand of rumpy pumpy, i would prudently go to a doctor beforehand and claim to be up the duff, in order to be able to stockpile the 'morning after pill' in advance..... i certainly wouldn;t decide to use contraception which might fail, then go running about at the last minute when it eventually does just that
but maybe that's just me. It seems so unnecessarily stressful not to do a bit of forward planning when it comes to stuff like this, is how i see it.
