It's not nothing not least because it's weird they had it specifically listed in the first place and then felt the need to keep that specification when updating the guidelines, but it's not nearly as dramatic as some of the memes make it out to be. The FBI updated their hiring guidelines and removed several things from automatic disqualification; among them, prostitution/sex work, Marijuana use & beastiality. They've all been adjusted 'down' in severity, so now you're allowed to explain the situation (up to some limits, beyond which is still automatic disqualification).

It doesn't disqualify you from the FBI any more.

The man said it under oath, so it must be true. 100%.

"they say beastiality is now okay" is reference to a policy change which no longer disqualifies animal fuckers from working there

They're just reiterating the official policy of the United States government.
