It won't happen, this is just fearmongering by people who are hellbent on fighting against an imaginary threat of a Christian Theocracy that much of the left believes is real.
The headline specifically says the Texas governor has signed this bill into law and there is a link provided for you to explore the text of that law which is detailed in the article. Child welfare service providers are now legally allowed to discriminate against LGBTQ youths and forcefully place them, along with other religious minorities, into Christian educational institutions. How many providers will choose to do that? Who knows. Probably not many, really. But, the fact remains, the Texas legislature and the governor have signed-off on this legislation that would legalize discrimination. There is no fearmongering about that. It is clearly outlined in the text, which anyone who is literate and possesses critical thinking skills could comprehend.
Could you point out then where in the text of the law it says this stuff? Because
from what I am reading(i.e. the bill as enrolled), it does not allow anyone to discriminate against youth, just allow them not to provide types of services that conflict with their beliefs. No one is going to be able to exclude gay children from a group home or anything like that. The bill says these orgs can provide children with religious education - something done all over the country - "in accordance with state law" - Not sure what the law specifies already but sounds like nothing new there.
