Really, they're all the same:

Happy International Men's Day to all of our male allies!

Happy Men's Day to the guys who support our message!

Only men who provide something to feminists and actively work for their social movement are deserving to them. It just reminds me again:

Only women, children, and dogs are loved unconditionally. A man is only loved under the condition that he provide something.

From Chris Rock. It's a good point. Only when a man provides something to feminists is he worth anything to them.
