"Doesn't mean either of the attacks were to do with sexuality."
Except the words used specifically were. If a lesbian had been attacked by other lesbians for various reasons, I don't think they would use homophobic insults whilst thumping her. The fact that straight women were alleged to use such insults is the homophobia, not necessarily the reason for the attack per se.
Just words shows you are totally missing the point, it is what comes out when normal restraints are off that shows what some people really think.
Try telling a black person who was beaten up whilst someone called then a black bastard, say, that it was 'just' words, and not racism.................
