> Plenty of celibate 'adult-lovers' prove that just because you can't get what you desire, doesn't mean you will act on it.
But there are also prison cells filled with pedophiles that do produce or consume child porn. Children _cannot_ consent and do learn from abuse. Homosexuality exploits exactly nobody across the entire world population. You said it yourself: pedophiles _desire_ something that we can all agree is harmful, and even if some individuals show restraint, exploitation happens. That's inarguable, and pedophilia carrying stigma is not unwise. Drawing a comparison between homosexuality and pedophilia blurs that distinction between and normalizes stigma against LGBT people. That community doesn't need or deserve any more demonization.
> As for your comparison with addiction, that is actually a victimless crime. Even procuring drugs (including harddrugs) doesn't lead to harm to anyone.
Addiction is a condition, and a lifelong one at that. You don't get rid of addiction, though addicts can live sober lives. In that way, it's not so different from a predisposition like pedophilia. I can empathize with both of these cohorts because they got dealt a bad hand and they can't change it.
Just because addiction shouldn't be a problem doesn't mean it is not, and just because drug use is "victimless" doesn't mean addicts and their families don't suffer and drug traffickers don't do terrible things. Have you ever seen the aftermath of a meth lab explosion? Or driven past the wreckage from a drunk-driving accident? What about seeing a family member fall victim to prescription painkillers, fueling an industry hell-bent on creating addicts? And then watch them sneak away in the early morning to withdraw money at the ATM so they can get a quick hit of something to take the edge off until they can get their prescription renewed because two pills doesn't cut it anymore?
Your final assertion might not be completely false, but it is a vast and undeserved oversimplification. People predisposed to addiction will always be predisposed to addiction. Portugal might have low rates of death from opioids and other drugs (because they're actually treating it), but they're eighth in the world for alcohol consumption. 3.8% of people in Portugal die from alcohol, which--depending on how you measure--can be more than double what we have in the US.
