Do you similarly believe that other forms of consensual sex which utilizes unequal power dynamics such as bondage or S&M should also be outlawed?
No, but I do think that they certainly shouldn't be encouraged or promoted.
(Fun aside: you'll never guess which sex almost always winds up playing the role of sadist and which one gets to be the masochist.)
Do you have any research regarding your fun fact?
The small bits of information I found suggested that about 50% of the survey group participated in sadistic acts while 50% participated in masochistic acts (with some overlap). Breaking this down by gender, 69% of women said they participated in masochistic acts vs 51% of men, while 45% of women said they participated in sadistic acts compared to 53% of men. Both of those numbers are fairly similar. Further, in terms of arousal through sadomasochistic tendencies, it seems that men tend to score more highly in terms of arousal for both sadism and masochism, meaning men tend to both find more arousal in domination and being dominated.
To your first point, whenever you have to recourse to "not all X's..." as an argument, you are clearly employing a strawman. You're highlighting possible rare exceptional cases as though they were the rule. As I have pointed out, 70 to 90% of prostituted women are sexual abuse survivors.
I feel you are dragging that statistic beyond its actual use. If someone is a survivor of sexual abuse, that does not mean they cannot make decisions regarding sex. I understand where you are trying to go with this, but the comparisons aren't 1:1.
