and your source measured the effects of one single area that cathartic theory is supposed to apply to, not all of them.
your source does in no way support the claim that the observed effects apply to anything other than aggressive behavior.
i understand that the theory supposedly applies to other areas as well, but as you so helpfully pointed out: the theory doesn't seem to hold up.
so either A: the theory is wrong, and so the association between aggression and sexuality needs to be called into question also;
or B: the theory isn't wrong after all.
you are now claiming that the theory is wrong, but at the same time, the theory is totally correct! (when it's convenient to you, that is)
so which is it now? is the theory correct? then your source must be wrong irrelevant.
or is the theory wrong? then the claim of a link between sexuality and aggression is also without support, until you provide a source for that claim.
you can't have it both ways, but you're sure trying to.
