a few points to that
to 2) Offending and Pro-C are 2 different things, most pro-c i learned to know here, might fight for these things, but do not offend or have offended they are just every day normal people
to 3) its an urge to express love and feelings for children not cause harm to them, this is what none of us want, also you can have urges and dont need to suppress them, there is legal material like lolicons to live out these urges without doing any harm.
