Why can't we treat this the same? Sexual feelings and abuse of children is obviously an illness and it can't be treated like many things. So we need to step up as a society and put safeguards in place
I don't agree.
It's obviously aberrant, totally unacceptable behaviour, but it's not an "illness".
Illnesses are conditions that otherwise perfectly well, healthy people succumb to, that respond to treatment, that you have a reasonable expectation of recovery from. These aberrant behaviours are the result of disordered personality, and those are not the same as "mental illnesses".
You're in danger of causing a conflation of two wholly separate things, and furthering misconceptions like mentally ill people being inherently dangerous.
Also, if you label paedophilia an illness, then there is a perfectly cogent argument that it should not be criminalised, because people do not have control over how and when they become "ill".
