I can see what you're saying and I do understand why so many people are upset over the choices, but I'm personally happy with them and think overall it's a good step in the right direction. I'm not sure what you mean with the insinuation that the female love options cater especially to straight men, though that might just be because my friend is quite happy with the amount of variety in the female choices for her to pick (Rhea and Sothis in particular, which surprised me, especially Rhea since I was wondering if the game was going to be a bit more... Conservative with her considering her ties to religion in the game?). I'll admit I'm a bit jealous there though since god, Raphael checks all the boxes for me aside from being younger than Byleth
I wish the choices were equal for both sides, that I do agree feels a bit like a double-standard on their part, and while I do see what you mean with the lack of a young alpha male-like character as a gay option being a shame I personally feel like Linhardt seems like a good choice as is in terms of being a bisexual student. In terms of Alois and Gil's status though I'm almost certain it'll make a lot more sense why they're bi options when we actually get the game and see how the story unfolds in relation to their characters. While I believe everyone's complaints here are valid, as a gay man I'm just happy to see two gay reps that are unconventional, it feels a lot more natural in a sense since they didn't seem like the types to be "obviously gay" if that makes any sense. I'm more than intrigued to see how IS handle their supports, who knows, they might turn out to have the best gay representation in the series up till this point. If this marks progress that IS will go forward with including more diverse queer representation in their future titles I'm completely for it.
Also, just a bit off-topic here but do we actually know if Claude can S rank female Byleth at all?
