This means one of two things: 1) you have met one, possibly two sets of gay parents
total (which I might actually believe because statistically you could not have come across that many gay parents) and that you certainly don't have enough information to make ANY conclusion on gay parents based on the few that you have met, or 2) you are lying by claiming you have met many gay parents (statistically a low probability), and that they are ALL abusers (a statistical
improbability).
