First of all, that number is not correct in the slightest. Second of all, no, kids are not being groomed into being trans, as you can see in the chart I attached to this reply the rate of left handed people went up significantly between 1910 and 1940, it was not because of a massive conspiracy to make our kids left handed, it went up because people were no longer punished for being left handed. and even if it was a conspiracy to make people trans, just why? what would be the point of doing that? and even at that studies have shown that gender affirming care benefits the well being of trans kids and is very very rarely regretted, so like if they're happy, what's the issue? it's almost as if the whole "trans people are indoctrinating your children" thing was made up because these people have no actual argument.

and again if basic acceptance of trans people is grooming show your kids basic acceptance of cis people to groom them back because that's still how you think it works
