Not really. At most, they're condoning "furries". Bestiality is intercourse with an animal, not anything that is non-human. By that logic, even having intercourse with a mer race would be "bestiality" because they are not human.
What defines a beast? Its not humanoid, its unable to give consent, its from a distinct species, and it does not have the same recognised rights as a Homo Sapien.
Therefore, Khajiiti and Argonians are not beasts, although they are beast-like in appearance.
Alien love is totally legal. They are humanoid. Khajiit and Argonian love is also totally legally. To recognise them as beasts would be to overlook their rights to life, liberty, and the pursuit of happiness. Werewolf and human love makes it onto normal television because the humanoid aspect is recognised as a clear distinction. There is a clear distinction with Khajiiti and Argonians from beasts. I would argue that Khajiiti and Argonians are human. If the difference between our DNA and that of a primate is 1%, the difference between Khajiit and Argonian DNA from Homo Sapien DNA would be less than 1%.
