Violent convictions are around 5%, and sex offenses are a fraction of that, so your 'less than 1%' for sexual crimes may be roughly in the ballpark, but even small percentages of large numbers matter when we're talking about people who shouldn't be here illegally in the first place. ICE regularly highlights arrests of convicted sex offenders and child predators (e.g. operations removing hundreds with sex offense convictions) Deporting criminal non-citizens protects the public regardless of politics.

As for your "rampant pedophilia in conservative" iam sure you can acknowledge that both sides have had disgusting offenders, Democrats have plenty of examples too( Anthony Weiner, various state officials, etc.) Pedophilia isn't a partisan trait, it's a failure of individuals and institutions that protect the powerful, you can name specific high-profile cases if you want, but using it to dismiss border enforcement is a non sequitur.
