People have to realise that consumption of any product, even in a passive manner, creates the demand and hence the market.
Once the market is established someone will find a way to supply. If you use child porn pictures you are, by default, condoning such pornography. A Tory politicians recent remarks, he sees no reason to imprison people for looking at child porn pictures, is not only ridiculous but wildly ill-informed.
If your actions cause harm to another then the law has no option but to punish you to the maximum that the law will allow. Helping to create the demand for such evil is causing that harm ergo. . .guilty.
Arseholes that do not think before they speak publicly should be similarly be responsible.
