*"Pro-lifers simply want to subjugate women" - This comes from the perspective of thinking natural feminine features like pregnancy and motherhood as inferior to masculinity. It is an important part of convincing girls and women that to be a fulfilled human, they should be able to call shots on the life of their unborn child. But simply, it's false. Holding people accountable for killing a life has nothing to do with subjugating them.
*"Pregnancy is a medical emergency" - Going back to considering natural femininity to be inferior, this argument often rears its head when discussing the exception a medical emergency. They say all pregnancy is a medical emergency in an effort to justify abortion.
*"It can't be murder if it's legal" - This is one disturbing argument I sometimes hear. Mentioning the Holocaust should suffice. If the debate goes beyond that it's probably a lost cause.
*"No uterus, no opinion!" - An empty slogan. Not many pro-choicers say this though and most of them actually publicly oppose it.
*"Banning abortion increases unsafe abortions" - This isn't false (while I am not sure about the numbers, I give it the benefit of the doubt). But it doesn't mean anything. All banning of crime is bound to increase risk for those who want to do it. For example, sex with underage people is (and should be) illegal, but people find risky alternatives to do it. Hopefully no one argues to legalize it to make it safe.
*"Banning abortions won't stop abortions" - Obviously. The law is in place to set a standard, and hold people accountable by that standard. All crimes that currently take place are not taking place because they are legal but because people refuse to adhere to the law.
*"Don't force your religion on me" - This isn't always manipulative, as some pro-lifers make the mistake of using their religious beliefs as the reason they oppose abortion legally. But mostly people are programmed with the narrative that Christians are the enemy (which is an important topic to address in the Western politics in general) and even when pro-lifers mention that religion is not the reason they oppose abortion, the response is emotionally directed towards the religion.
*"The Bible approves abortion" - This is tied to the narrative that Christians are always behind opposing abortion for religious reasons. The effort here is to manipulate them into becoming pro-abortion because the bible is supposedly cool with it. I won't go into whether the claim is true or false, but it's interesting that most people who say this are against using the bible as the foundation of legal discussions.
*"Don't want an abortion? Don't have one!" - This is like saying "don't want rape? Don't commit it!" trying to sway people away from legally banning a violation of human rights. No, some acts should be legally banned and are beyond personal preference.
*"Pro-lifers shouldn't eat meat" - This is simply a result of seeing human life as equally valuable as animals. Not many pro-choicers say this, but I believe they don't see a problem with the argument because devaluing human life without directly saying it is convenient for pro-choicers.
*"Pro-lifers should be against gun ownership" - This argument usually comes after some mass shooting tragedy. It's an emotional manipulation used by politicians to justify confiscation of guns, which is not only unconstitutional, but clearly against the human right of self defense. It's another version of trying to convince pro-lifers to support unrelated issues using the word "life".
There are many others obviously, and I might add as remember, but these are the usual horrible arguments I see repeatedly.
The pro-life response isn't alway good, unfortunately. Some pro-life politicians have said things that I think empower the pro-choice accusations. We should always remain logical (always check if your own logic is sound first),
Abortion is the heart and mind issue of our time so the responses should be focused, refined and patient as well. And, again, peaceful.
