[Opinions] Lex is an awesome nn (m)
and to my ears it's about the least 'effeminate'* shortening of Alexander available, now that Alex is so common a girls' nickname and Sasha is commoner on girls than boys. There's Xander, I suppose.
I think it's a brilliant NN, especially as my first association for it is Lex Shrapnel, a British actor who I recently saw perform in Shakespeare's Histories cycle and loved. That's got to be one of the coolest names ever :D
* Out of interest, would you take the same kind of issue with a very 'masculine' nickname on a girl? I don't mean to cause offence, it's just that a lot of my favourite male names regularly get described as 'effeminate' and therefore bad, by people who simultaneously acclaim boyish names on girls = strong. The double standard really gets me.
