The general argument of 'kids don't know any of this anyway' is really, deeply, wrong. If kids don't get anything from these readings they wouldn't get anything from other readings. The objection would be to read hours in general, not drag reading hours.
And if you think reading to kids does nothing for them, then you're trivially wrong. Kids aren't unthinking robots until they are ten or whatever the 'does nothing' group thinks. That is such the feeble handwave.
Your reading comprehension leaves much to be desired. Nobody has said that reading to kids does nothing for them. Nobody, not at all. That's not even in the same hemisphere as the arguments being made in this discussion.
The point is that kids get nothing from the reading being done by
drag queens specifically. The
drag queen aspect of this entire thing is completely unnecessary, and as Thermal has said -
not for the benefit of the kids at all.
Let me try to add some framing, and perhaps you will be able to follow. I'll do some "for" and some "against" situations.
For: Diversity Story Hour, during which people of different orientations, different family compositions, etc. read to children, each reading a selection that touches on their own manner of diversity. For example, there could be a married gay male reading a story about how an adopted child has two dads and that's okay.
Against: Butch Lesbian Story Hour, during which ONLY butch lesbians are showcased
For: Costume Story Hour, during which people in a variety of costumes read stories to children relevant to those costumes. This could even include drag queens.
Against: Furries Story Hour, which focuses ONLY on people who identify as furries.
For: People of the World Story Hour showcasing people of many different ethnic and cultural backgrounds, reading stories from their backgrounds
Against: Black Story Hour, which features ONLY black readers reading only black stories
For: What Can I Be When I Grow Up Story Hour, featuring people from a variety of different professions and vocations reading to children from stories that touch on those professions. This, again, could very happily include a drag queen alongside a firefighter, a veterinarian, or whatever else.
Against: Plumber Story Hour, featuring only plumbers reading plumber related stories.
Are you catching the pattern here?
