I think it is a fair reason for skipping on the game (or holding out on picking it for a long time). Not related to Fire Emblem, but I promised to myself that I am not buying Persona 5 if ATLUS doesn't give us a female protagonist again (girls and boys who like playing as female characters were completely neglected in Persona 4 and Persona Q, after Persona 3 Portable having full-fledged different paths for both male and female protagonist)... It would be amazing if they acknowledged the LGBT community and decided to give us the option to date characters of the same sex, since there are gay characters in some of their games, but I have little to no hope of that happening. So yeah... Aside from complaining in the internet, signing petitions (which do not really work with Nintendo, but at least it serves to make them aware of the problem), the best one can do is "vote with their wallet". If you don't like the way the developers did something in a game, then don't buy/support it. I do think Fire Emblem Awakening does a lot of things right, so even if the game doesn't give us the opportunity of pairing characters of the same sex, it is still a great game and it would be a shame to not play it.
