If it matters to you, yes. You should encourage more males to go teach if you find that important, and it's a cause that you support. You don't have to support every cause, but you also don't have to dismiss those that others find important.

Both my little ones have had male teachers (K and 3rd) and I though they were excellent. My oldest is in college and considering teaching, which I think is wonderful. I encourage him to pursue it because we need more good teachers.
