What should pro-choice men be doing to be better allies?

Anonymous
I am pretty hard to convince to change my viewpoint, so if you're bringing a pro-life argument please just save your time and don't bother.

I am asking this because I've heard the sentiment that "men can't have an opinion about it," and "no uterus no opinion."

It makes me feel like I'm not allowed to care or have sympathy of any sort?

It's a traumatic experience to go through with one, but I feel the choice should be there as a physical & mental healthcare option. No one should be forced to carry a child to full term if they do not want to. But now that seems to have been taken away, where I live. Side note; do trans-people get to voice their concerns?

I'm trying to figure out if I need to donate, attend rallies, or simply vote more. But I think ultimately I just need to know why telling me to shut up is the most common thing I hear?

Am I missing the point? Bear in mind I'm like half autistic so I'm just wanting a straight answer, in plain terms without sass.

I'm leaving the option to answer open only to self-identifying women, to limit blue trolls and such.
I am asking as genuinely as possible and will read each reply. I'm trying to educate myself even further and Google isn't helpful and the people in my life aren't supportive or understanding.

I also want to apologize to the blue trans accounts that aren't able to reply to this. I was tempted to leave the conversation fully open but decided last minute not to.
