No, it is not: equating homosexuality with paedophilia is like equating heterosexuality with paedophilia or, rather, family, or church, or even schooling, with paedophilia... it is not a slippery slope as much as a wild flea hop.
The "slippery slope" you point to would be more like suggesting that watching or reading crime fiction leads to "real crime" or, at the very least, is a sort of wicked, morbose perversion.
So, for you, it is perfectly reasonable to speak of violation of law or of privacy, but it is wildly metaphoric to speak of the violation of an avatar?
The true "slippery" slope is to consider reducts or contexts in which something is considered "real" and, therefore, liable of prosecution, like when black or common people were not considered "real people", or animals did not suffer "real" pain because they were not "real" beings, being soulless... or considering that there are ages after which you are, magically, rational enough to receive the Holy Spirit, or "capable of making a prudent decision", consent to any sort of sexual relationship, or even be considered a "viable" human being... or considering that being politically active can make yourself responsible for any sort of terrorist or dictatorial crime against you, or that being raped "in the real world" can only be, somehow, your own responsibility and choice relative to the way you dress or the way you conduct yourself.
As if the world of "intentions" or "reasonabilities" were not slippery enough slopes already in regular law practice.
