Less social pressure to play with gender-sterotypical toys != social pressure to play with opposite gender toys.
> A 2017 survey from Pew Research Center found that a majority of Americans considered it a "somewhat or very good thing" to steer kids toward toys and activities traditionally associated with the opposite gender (though respondents were less enthusiastic about doing so for boys than girls).
Yes, not only was parents doing that recognized as common-but-not-dominant thing 50 years ago (as a near-50 GenXer, I was aware of it existing and being perceived by adult society that way as a kid), it was even before that a popular media cliche leveraging a social trope that it was a real if eccentric recurring pattern (especially by fathers without sons toward girls) even earlier.
I think you're off by several orders of magnitude, but yea it goes back a long way lol
