I think if you are opposed to the CHOICE (i.e. likelihood is you are opposed to a c section when otherwise healthy and able to birth naturally) that's fine - give birth naturally. BUT if another woman CHOOSES to have a c section for the birth of HER child, then so be it. Why should someone else's choice affect others?
I don't agree that 'cost' can come into play unless of course you also oppose; gastric bands, sex change operations, breast enlargements and reductions, genital enlargements,cosmetic surgeries (yes, some can be on the NHS depending where you are from) because all of these are 'mainly' lifestyle choices. A gastric band ultimately reduces the size of the stomach so you eat less. (Or to put it 'cheaply' eat less!!)
Also, there are medical needs to needing c sections that may not be physically obvious. There may be a psychological issue. Not all can be resolved and the only 'choice' for these women is a route that does not interfere with their mental health and well being. These are not people who are 'too posh to push' - as described by some in the comments section of the daily mail, but simple women who have fears and phobias. You're not likely to force someone outside when they have a fear of open spaces or tease someone with a spider when they have a fear of them are you?
I agree that their should be a choice. If you don't want a c section, then don't have one! Simple! But don't force others to hold the same opinion as yourself by DENYING them a choice.
I personally have no opinion as to a c section or a natural birth, mainly because at 31 weeks with my first child, I have absolutely no idea how I will cope. I cannot (nor can anybody else) say with certainly what will happen. I bet MOST of those who had a c section didn't envisage having one - most end up that way due to complications. I have heard many, many stories about giving birth naturally and via c section. I can say, with hand on heart, no birth story has EVER been the same. Some (like my SIL) have given birth with no complications, no tearing etc, etc yet some have needed extensive stitching and in one case of a friend, reconstructive surgery. Some have healed well and quickly after a c section whereas some have taken longer and have been in more pain. It all depends on the individual.
I think with me, I can see advantages and disadvantages to both. It depends on how you rank them in your own personal life. I may need a c section and I may not. A scan will determine that. But it doesn't scare me - likewise with a natural birth. If I need a section, so be it. If I don't, then it's natural all the way. But I won't ever say NO to a c section, if at the time I feel like I'm not coping. Time will tell. I will feel that I have control if the choice is there.
Your birth is not going to be the same for everyone else. Let people make the choice that is best for THEMSELVES.
