Sure, I agree that it is not the only pro-life position, but it is also not an extreme position among pro-life people (per some Pew research that someone else was quoting, approximately 37% of pro-life people don't make exceptions for rape, 36% do consider rape an exception, and 27% say it depends, whatever that means).

I also think it's reasonable to expect that those who actively campaign to ban abortion are more likely to have more extreme positions than those who simply passively accept these positions. I also think their positions are very relevant, as they have proven to have more sway over public policy than the majority of the population - so combating their arguments is more improtant than combating the beliefs of the more silent pro-life majority.
