Because I said that a underage girl is beautiful?
Dont know what is so wrong about that. I would agree if I had make any sex/rape jokes, but I didnt. She will turn into a beautiful woman.
That is a fact.
Did you forget the part where you said you are probably in love with her? Generally, 14/15 girls can be pretty/cute, 16 some middle ground, and 17 is when they start being hot. This was the case with Suzy and I find it is often true. However, mere estimation of looks is very,
very different from suitability for a relationship. You aren't talking about some idol girl and how nice she is on stage, you are talking about some girl you know and the notion of an actual relationship. These are extremely different things.
As for your justification of using future tense, it doesn't work because you are speaking it from the thoughts you are having right now. What if you said that about an 8 year old? Is that past your personal boundaries? Does it just feel wrong to be considering them like that because it's ahead of their time? Most other people place those personal boundaries quite a bit further on, like say, girls old enough to date them.
I do think a lot of guys have at some time felt a little something for a younger girl despite these things, but in such a case you control your instincts and imagination with reality and wisdom, not publicly announce your love. Fleeting feelings are not all of what life is. You should be respecting where that girl (not woman) is in her life and focus on your role in relation to her as a man (not boy) rather than how you would be relating to her differently five years from now. Why? Because she is a person here and now, not just some image of a prospect.
Seriously man, get out of fantasy land.
