"The determination that you shouldn't go is a good indicator that you probably need to."
Sorry but that just seems like all you're doing is shutting down discussion on the subject. If a man disagrees with what you say, you take the disagreement itself as proof that you are right and that man needs to go on a course. Determination not to go isn't an indicator that you should imo, it just means you don't want to go to the course.
"If they thought consent was more important than their own feelings, they'd either go."
I don't think it's a case of putting their need above everyone elses. It's their choice whether they go, and you don't need them to go, so why shouldn't it be up to them whether they do go? What if they didn't want to go to the course, but agreed that consent was more important than their own feelings?
"Female needs and boundaries coming second to male desire... Rather reminds one of something, doesn't it?"
Wanting a man to go to a workshop is not a female need, so he's not putting your needs second with his desire not to go. I'm not saying that this course is pointless, I can see it being very useful in some cases. Some men would be happy to go for whatever reason, maybe they already feel they know enough but will go on the off chance that they pick up something, others may not be totally confident in their ability to tell when someone is consenting and would like to explore the issue of consent in a safe environment where they can learn about things. But there are others who would chose not to go, and that refusal to go can't be treated as an indicator that they should go imo. Not going to a workshop about consent doesn't mean you oppose the right to consent/not consent itself, it just means you aren't going a workshop on it.
