@nautilee really? I've seen plenty of people using it in what doesn't seem to be a slur sort of way...
@nautilee including at least one person I normally trust to be pretty knowledgeable about that kind of thing
...well, everywhere I've seen it used and in common parlance, it's a slur. and it originally started as shorthand for a slur phrase.
@nautilee ...I remember hearing that it was a reference to the egyptian god thoth
