Yes, and I do fault them for that, but only to an extent. Wedge issues are a valuable commodity, aren't they? Republicans certainly kept banging on that pro-life drum (which supposedly no one really wanted and y'all were just yelling about to keep the rubes on board?) The flip side of that was that you all looked like extremists. (But Roe is dead and buried, so I guess you're doing Nazis now. We all sort of hope that's cosplay as well, but... look at Roe. Someone might start to suspect you're serious.)
I guess there is such a thing as a slippery slope.
In any case, "you had 50 years to make a law about it" seems like a silly argument if the right in question is protected by the constitution. Every SC nominee in recent memory has testified to that specific question under oath.
And what sort of law are we talking about here? It's far easier to restrict a right than it is to affirm it. It honestly makes no sense practically or politically. The only way to attack that right was through a challenge to Roe, so that was how things went down. They had to overturn Roe. Took half a century. I guess that's something.
