In Out, Shake it all about…

Seriously…If anyone out there has a non hysterical reasan for being either IN or OUT of the European Union…please let me know? I am so confused, I can see reasons for being in & being out. However, the leaders of bothe sides of the referendumdom are foul & lothsome to me. So please advise……at the moment I feel I can only spoil my ballot paper….
