You don't think there's a possibility that Trump is MORALLY WRONG on this issue, and that people are upset about the GOP front-runner lowering the moral bar (perhaps permanently, since raising it is fiercely hard) for the entire GOP?
Example: suppose Trump were to personally approve of one, particular abortion. Would that "change anything on a grand scale, politically"? After all, 1.5 million children are dying by abortion in the USA every year... what's one more? Answer: it's catastrophic... not because of the statistics or political numbers or because of the number of words typed about it on blogs. It's catastrophic because it's the unjustified consent to the death of one innocent, whereas the consent to that single murder wasn't there before. It's a change from "all life is sacred" to "that person over there can be murdered with impunity, and I approve this message".
Rebecca Kiessling, a lady who was conceived in rape, puts it succinctly: "The people who want 'a little exception for rape and incest' are really walking up to me and saying, 'If I had my way, you'd be dead right now.'"
...and you seriously suggest that people are upset about this out of simple BOREDOM?
Like I said, I don't support the abortion exceptions. However, I'm aware that many Republican politicians like GW Bush had this very same pro-life position and I don't remember there being a reaction like this. As for the bathroom thing, I also don't agree with Trump but he's clearly thinking of it as a businessman. Having to build three bathrooms is a difficult thing for businesses. I just think it's all getting blown out of proportion. And with Prince dying today, it's probably going to get mostly lost in the shuffle.
