And I take issue with the fact that Jack (and by extension myself) being open to sleeping with a large variety of people and remaining unconvinced by monogamy casts a bad light on all bisexuals.

I'm hardly 'convinced' by monogamy myself, as I proudly identify as poly, albeit I'm currently in a monogamous relationship. However, I have no problems with commitment - polyamoury and commitment are not mutually exclusive!

And while I might be open to sleeping with a large variety of people, I always reserve the right to choose who that will be - I would not ever, even if I were perfectly free to do so, be willing to suspend my right to pick my partners based on my criteria. Sleeping with 'anyone, anywhere, anytime' effectively states that I use no judgement in picking sexual partners and would happily sleep with literally anyone at all who was willing to.

I don't like being likened to that trope, which is now associated with Jack, mainly because I find it very offensive that an inability to commit and a desire to sleep with anyone at all is automatically associated with being bisexual. It's simply not true that all bisexuals are like this, in fact I would say very very few are.
