Just cut out the "for Child Abuse" part. They want to scan people's private messages. The reason doesn't matter.
These politicians couldn't give less of a fuck about children. Politics and children do not belong in the same body of text. Finding the words "child", "terror", "drug" and "money launder" in any political text is evidence of bad faith and a perfectly valid reason to completely dismiss whatever's being said. It's almost certain they're trying to manipulate people into giving up freedom for false security by appealing to the eternal bogeymen of society. Communists were that bogeyman once.

Said something like "I don't support opting in to pedophilia"
It's completely wasted effort and does nothing to stop pedophiles or to protect children.
