As an aside, the amount of patronizing in these comments along the lines of "but these women will clearly take the medicine wrong or fail to understand the consequences of their actions if we don't have them speak to a doctor first!" is just... really telling.
I'm terribly sorry to have read your experience. I empathize deeply, though my situation is different (migraine medication vs birth control), in my experiences in having dealt with doctors and insurance companies to get both the medication I need and in an amount that will get me through.
I hope this change and others like it help bring you comfort and safe, affordable access to medicine you need.
Availability and discovery are absolutely massive to health services. Most people don't know about their options, and many more don't even have the option in the first place.
Having this be OTC is a massive step in that regard.
I have a feeling you might be the type of person to think government should get out of the way of most things. Why is it not such a big deal in this case?
That said, I do believe there is a massive overuse of hormonal contraception which is partially contributing to several negative factors in society right now. This should be addressed through education and informed consent (the Rx process isn't really doing this either, so...).
First of all: are you the person affected by this change? If you aren't, try and imagine being a person that was. If you cannot empathize at all with the other side, perhaps it isn't something you should be arguing for or against.
Second: does this vibe with how you would treat someone you normally would disagree with politically, if the position were flipped? Say there is something you think government shouldn't have a say in (apparently not family planning, but you can think of something... guns? business?) then have them argue 'it isn't such a big deal to have to jump through this bureaucratic hoop and the reasons we make you do this is are obviously not as overt as we pretend'. How would you feel about that argument?
