Count how much times Domon cried. Now count how much times Kamina cried. Also, are we talking about the sub version or the dub version? In the dub he sounds like a crybaby. I don't know about the jap version.
Protip: There's a big difference between manly tears and girly tears. While it's true that Domon shed quite a few manly tears, he also shed a lot of girly tears.
