I think when systemic structures that give power and privilege any one sex over any other (including those folks who do not identify on the binary) are eradicated, not simply replaced with a different set of sex-based powers and privileges, then yes, we would be able to say that sexism has been rooted out. That would not mean that sex-based prejudice would cease to exist, as they are very different things. Additionally, yes, you entirely walked around it. Engaging with it would have meant taking time to read the references I provided, understand the perspective presented, and at the very least, provide some insight as to why you insist on remaining with your preferred definition - while I have no way of knowing if you've done the first two, you definitely have not done the third in this conversation. By choosing not to, and remaining with your own definition, it seems to me you are attempting to control this conversation and bias it in your favor. Your arguments only prevail if your definition prevails, and by not honestly engaging in consideration of the definition I've provided, you've shown that you're not interested in actual discussion, but "winning" the argument.
