Um, three issues here. First, many and perhaps most arguments are inherently binary. In this case, is coerced birth control for welfare recipients a good policy, or not. That doesn't mean there are or are not valid arguments on either side, it simply means that adopting coerced birth control for welfare recipients as policy is mutually exclusive from not adopting coerced birth control for welfare recipients as policy.
Second, no one here is choosing slavery; there IS no legal slavery in the USA. We have some people who embrace welfare as a better life, true, but they are not in any way slaves; they remain free to end their time on welfare, or move to another jurisdiction, as they wish. They can weigh 100 pounds, or 1,000 pounds. They can have no children, or seventeen. Some women on welfare choose to have additional children as a means to a better life, but that isn't slavery. Of course I see many things wrong with that decision, but again. slavery isn't one of them.
And third, I didn't invite anyone to ignore you. I even defended you.
