i think samandi most people have looked at the info in the link, which may be skewed but is all we have without resarching further, and concluded that they encouraged him to dress etc opposite to his sex and forbid him chosing items they disliked / opposed (combats), which is not bringing him up gender neutral / giving him a choice
"For the past five years Sasha has alternated between girls? and boys? clothes"
It's there in black and white, four paragraphs in. So yes he was encouraged to dress in "girls' clothes" but presumably he was also encouraged to dress in "boys' clothes". Not sure why the combats were banned.
Incidentally this sentence:
"Beck was resolute and encouraged him to play with dolls to hide his masculinity."
sounds absolute rubbish. Plenty of boys play with dolls, they don't do it "to hide their masculinity".
