Esperanto, pros? Cons?

What are the pros and cons of learning esperanto?
Is that language even useful? Isn't English good enough?

Pros:
Supposedly pretty easy to lear

Cons:
2 millions speakers, if you stretch . Hardly anyone knows what it is (as opposed to if you could say you speak German, you'd get some real respect).
It's gay

Pros: you get a green star.
Cons: gayest language ever. It's just a bunch of European languages mashed together.

I don't like its gender system.

Most masculine roots may be made feminine through the addition of the suffix -ino, and made to describe a group of both males and females with the addition of ge-. For example, patro means "father", patrino "mother", and gepatroj "parents", but gepatroj cannot be used in the singular *gepatro for "parent". For these gendered words there is no easy way to make the singular neuter equivalent

WTF is that? woman-father  IMO is hermaphrodite parent, not mother. But looks like esperanto is not cool enough to have concept of hermaphrodite parents.

Ok. Being heterosexual then I don't have to learn esperanto, got it.
