Not sure whether May's stupid or just wants to ban online pornography in the UK.
Or, perhaps, she's been promised a few quid by those in charge of UK-based pay-for porn sites? Since virtually nobody* is going to pay for pornography then I can only suspect that Ms May is either a moron or wants to try to ban free pornography.
While I'm not as against the "dirty old man register" one must sign up to in order not to have innocuous sites blocked by association at least that is vaguely possible. Though, again, one has to wonder whether the banning of such harmless content such as face-sitting is an attempt to block all non-UK produced porn.
So, there we have it, the only possible explanation, unless Ms May is a pathetic, moronic, puritan fascist pig, is that she's in the pay of the UK porn industry.
