IIRC FE7's English translation is a pretty faithful rendition of the Japanese; I remember reaching their supports as a child and the implications completely flying over my head until much later. :P
As for the entertaining Ike/Soren debate, let's try to take this one thing at a time.
No it doesn't. Have you read it? If not, you're misrepresenting a dissenting opinion based on your assumptions, not facts.
This has always been a weird line of argument to me, because the 3 possibilities (1. Ike is asexual 2. Ike has gotten with a woman 3. Ike has gotten with a man) aren't mutually exclusive. I can talk about Priam more, though.
Just to get the record straight, I don't think a female character has to be a serial womanizer to be plausibly gay (or potentially attracted to other women) and I feel like the same could be said for a male character.
I feel like your argument was stronger before your edits (though Anri says hi), but if you're going off the assumption that 1. Awakening canon has bearing on Tellius canon 2. Priam's claim can be taken at face value and 3. There's no chance of Priam's situation bearing any similarity to Marth and Anri's, you still have to defend the claim that Ike procreating precludes the possibility that he, at some point in his life, entered into a romantic relationship with Ike or Ranulf (or any unnamed male suitor :P).
