I find that the best method for reaching libs (or anyone really) is to not lean into the current ‘hot topic’ but rather lean into or bring up topics that have been ‘set aside’ by the mainstream narrative.

For example —

Hot topic is Ukraine War? Talk about Covid instead.

Hot topic is Abortion? Talk about Ukraine instead.

Hot topic is Vaccines? Talk about Abortion instead.

Every time the new ‘Hot topic’ hits, change strategy.

Why? Because as you point out, it’s very hard to discuss any topic when it’s currently emotionally charged up to 11.

Conversations go much easier, it’s less divisive and it short circuits their brains a little bit.

When the new Hot Topic is now about what you discussed before, the lingering discussion will be in their minds.

True that, but there should be an issue relating to pain- An animal is treated cruelly and painfully, and we justly fight for the abuser to receive justice, and as you yourself said:

The abortion debate and the vax debate are two distinctly different arguments, because one involves choices of the self alone, and the other involves choices that also affect another 'person'. (I just put it in quotes because this IS the argument, is whether the pre-birth baby is a "person".

Third term abortions should end, granted. I would go further than that- Even as early as eight weeks, a pre-born Child may feel pain, so this should be considered. State's rights should have plenty of say, but not after the second Trimester.

As far as Planned (un) Parenthood goes, there are plenty of alternatives: https://www.dailysignal.com/2015/08/17/planned-parenthood-loses-government-funding-heres-map-health-clinics-take-place/

Funding PP is a Congressional issue, and in particular the House. Even CNN Reported that, when abortion is singled out as a Planned Parenthood 'service' , a large majority of voters do not want it funded: https://www.cnn.com/2009/POLITICS/11/18/abortion.poll/index.html?_s=PM:POLITICS

I would be inclined to believe that the numbers may even be higher than this, since there has been some activity to win hearts and minds on the pro-life front since this poll was taken.

In this situation, the arguments you outlined, it's best to define what a person is, and define the effects.

The vaccine is clearly shown not to prevent transmission or infection. Because cases would be non existent if it did, with the vaccine rates they continue to claim.

So it's possible the vaccine may help prevent another person from getting sick, or it may not. It may also kill or debilitate you, but it may not.

An abortion will kill the child growing within, and while I do understand the "clump of cells" argument to a degree, they are absolutely living cells.

So you can guarantee a death with abortion, or you can take a very minute risk by avoiding the vaccine.

It seems like an easy choice to me. One DOES affect a life, one MAY affect a life even in best case scenarios.
