Porn, addiction, sodomy, AIDS and STDs aren't immoral, and suicide isn't as black and white an issue as you make it out to be. Porn and sodomy harm no one, what someone does or watches in his own home is none of your business. Addiction is a mental illness, and thus cannot be labeled as 'immoral', any more than schizophrenia or depression can. AIDS and STDs are diseases -- how, exactly, can having a disease be referred to as immoral? If you're saying that the sex that leads to becoming infected with these diseases is immoral, again, sex cannot be immoral unless it is adultery or rape (and in the case of rape, the victim who becomes infected has done nothing immoral; as for adultery, it is the act of cheating on one's parter that is immoral, not becoming infected -- no one chooses to have an STD, save for those wackjob bug-chasers). As for suicide, again, this is often the result of a mental illness or acute mental stress, which certainly isn't the fault of the person who does it. In cases where a person is in a great deal of pain, with no chance of ever getting better, and in fact will only get worse and worse, you really can't judge them for wanting to end their suffering.
Using sodomy (anal sex) as an example, you may not personally enjoy it -- neither do I -- but you not liking something doesn't automatically make it immoral. A lot of people agree with me that the colour orange is hideous -- that doesn't make liking it immoral, does it? The basis of morality is A) Not harming someone needlessly, and B) Treating other people with kindness and respect. Frankly, YOU are the one who is immoral.
As for infanticide (which is NOT the same thing as abortion), rape and adultery, pretty much all people, whether religious or secular, agree that these things are immoral. Interestingly enough, your own bible promotes ALL of these things. Thankfully, most Christians don't agree with the bible on these things, as most of them haven't even read these passages, but the fact remains that YOUR God promotes murder, rape, violence, torture, slavery, etc.
