Do mixed Martial Arts competitions really compare to Cockfighting from an ethical point of view?

I read this today, and I think the comparrison between animals thrown into a pit/cage with no choice but to fight is far from the reality of people training with the purpose and intent to fight.

So from an ethical point of view is Cockfight really an accurate comparison to Mixed Martial Arts bouts, or just a shock tactic aimed at disgusting people to gain public support?

Unless the humans in the fight are being forced to do it, then there is no comparison.
