WHY are celtic fans so agressive?

i have been with yahoo for a while now and i have yet to meet such vile creatures as adele and anne marie who gave me loads of personal abuse when i asked a question on here of which i got a solicitation for! WTF, i was the one being abused they have also been calling me an effing bigot on my other questions in other sections, i have asked yahoo to look into it, does it really make you feel good to be such horrible people??
