Ah ok, so it's a relative thing - I'm genuinely curious as some things are ethically binary and some are on gradients (this sounds like the latter).
Eg how many rapes, murders etc are 'ok' in the UK - most people would say zero is the minimum, whereas how many military deaths in war are accepted is more of a gradient and depends on the situation, rationale etc
So I guess you're saying you want to minimise animal deaths/suffering in farming due to the volume, not the act? ie let's say there are 500,000 animals killed on the roads each year, I assume you wouldn't be ok with reducing animals raised for food to 500,000 a year? (you'd still push for zero).
In a similar notion, I assume (but happy to be told otherwise) that you don't have an issue with the millions of 'natural' deaths each year in nature (eg cats, badgers, ferrets, hawks, owls, foxes, hedgehogs, pike, perch etc etc pretty brutally killed animals every night) - I assume you wouldn't want to start controlling nature - eg you could try and stop predators catching animals/causing suffering etc.
As I say, not having a go - just genuinely interested in your moral compass on this:
1) Are you trying to reduce suffering of animals as much as possible (in which case you'd want to stop farming, driving, predators hunting etc)
2) Are you trying to stop humans causing animal suffering (in which case you'd naturally be open to stop farming, driving, having pets, horse racing etc)
3) Is it less about the suffering, more about reducing meat consumption ( in which case it's just the farming bit)
Obviously all the above are on gradients depending how serious you are - eg Greta Thunberg is so serious about climate change she thinks we should all instantly stop driving, using factories, shut power plants - most people kinda accept they'd prefer to cause a bit more environment damage in exchange for less disruption and change at a slower pace!
Likewise, to be vegan I'd imagine it's pretty difficult far beyond food - your banknotes use animal fats, your car using animal skins, shoes with leathers, wallets, beer uses fish swim bladders, candle/soap with tallow, your house is riddled with animal products used for its construction etc etc... it's an interesting measurement as to 'how far' each person takes it
