There is no other preventive measure. Abortion, a response to conception, is remedial by definition.
How dishonest. We're cleary talking about preventing suffering and greater violence, not preventing conception (although, abortion is the only reliable, widely legal way to prevent the individual themselves conceiving).
I did not bring up gambling.
My question wasn't "who brought up gambling?"
I am worried about initiated violence.
If you were, then you'd be worried about the initiated violence of survival and birth, not just conception and death.
Of course I would try my best to never use force, but instead only act in response to cues from them. I may not be flawless in this. But so long as the infant is not my offspring, it is not my fault for being an imperfect carer, as I am dealing with a problem that I did not create. If I were the infant, I would feel respected by any carers who did not conceive me but who are sincerely trying to figure out what I want from them, certainly more than I would feel respected by aborters who (just like conceivers, and just like tyrannical parents) think they know better than I do.
"who think they know better than I do"
This is the position you take every single time you use force.
When you pin a baby down and force a diaper on them,
When you cram them into a carseat or force them into a jacket,
When you grab them from a dangerous ledge, stop them pulling a heavy piece of furniture onto themselves, or swipe a button battery out of their mouth,
They might be screaming and trying frantically to escape. That's clear communication. But you do it anyway, because you think you know better than they do.
I sincerely wonder why you think it's ok to commit violence to preserve life, but not to create it?
Now you sound like every tyrannical parent justifying prohibiting their offspring from dating.
This would mean ongoing violence and emotional pain. Again, this is far more similar to what you're supporting (repeated acts of violence for unrequested life preservation).
Then why am I opposed to conception?
Because you're inconsistent.
