I was unaware Republicans ONLY wanted abstinence taught in schools. If I'm not mistaken, they wanted abstinence INCLUDED in sex ed as PART OF birth control -- after all, it is the only form of pregnancy prevention that works every single time it's used.
Get your head out of the sand, it wasn't left wing people who wanted abstinence only education, it was right wing. And no, not all right wing people wanted abstinence only education, some did. Point was that it was something that came much more from conservatives, not liberals.
The issue is Democrat/Liberal/Progressives don't believe in teaching abstinence, because it involves behavioral self-control and recognizing there are options other than having promiscuous sexual intercourse without worrying about the results. They tell lies (say it isn't so!) that those wanting abstinence taught want that AND NOTHING ELSE taught. There may be some small town exceptions, but you can't say "Republicans" and have any facts to back you up.
Some conservatives, not all, see above
"Abstinence-only education programs, in contrast, received the lowest levels of support (36%) and the highest level of opposition (about 50%) across the 3 program options. "

And since you like graphs

Whether you're talking about pregnancy, STDs or HIV, abstinence PREVENTS a lot of problems. But the Libs want to live unfettered by morals or consequences as long as they have access to every possible SOLUTION for the problems they create.
Abstinence would work great at stopping STDs and unwanted pregnancies, to bad it has never been shown to be an effective model for teenagers to follow. Ideals are great but be realistic, abstinence only education has never been shown to produce the desired results.
Liberals: We don't want the government in our bedrooms or medical decisions.
EEF: The Republicans are not doing enough to prevent unwanted pregnancies.
Your argument makes no sense whatsoever. The point is that if abortion is murder and must be reduced as much as possible then you don't fight against sex education which is going to help reduce the number of unwanted pregnancies. It is like protesting house fires but not wanting people to have smoke detectors and fire extinguishers.
