To all GW fans:why do people argue about this?

i read this one article about the yaoi and non-yaoi about gundam wing, and this person was against relena and heero being paired. and also i heared some people that likes relena and heero being paired. why do you think is a problem between them? it's confusing me. do you think there are fake arts of gundam that is mainly posted in mag and in the internet? why do the officials isn't even responding to this misunderstanding and give them the answers between such relationship (1xR)? is there any possible reason that heero is gay? just wondering.
