I can't imagine that kicking a rooster would possibly do that, unless you've crossed the line to abusive in force.
Personally, I 'kick' my roosters if they get out of line. They ARE NOT hurt, they are not terrified of me, and I can keep just about any rooster toeing the line that way. By kick, I mean push out of my space with the same force that you could do by reaching down and shoving them with your hand. Feet are safer for the human, though. If you have a borderline mean cockerel, your face and hands shouldn't be down there!
I definitely do NOT cross the line into abusive force just enough to make him respect me and my space, just like you say.
