There is one aspect to this no one has mentioned yet as it is only tangentially related. I am certain there are some -perhaps many - politicians who can see that it is a poor idea and would argue and vote against changing 230.
Except for one thing. During the next election cycle, that would get reduced to one sound bite, one phrase, "Candidate Jones voted agains making life harder for child predators and sex-trafficers."
Voiting against useless measures and protecting civil liberties in the process - especially on hot button issues like sex offenses and trerrorism - is often political suicide. This is also another reason that term limits should be enacted. When you only serve for a set time, a person may be more likely to work in the public interest instead of feigning it for their own political gain.
Edit - spelling and to add: Where are the term limits Trump promised. I never expected him to be able to pull it off, but is he even trying? It was probably the only populist idea he spouted that I could actually get behind and support.
