writing to your representative and having fears or repercussions is normal...
old trick is to relay your thoughts about "someone you know"

Other people may prefer to write their representatives using the "give me liberty or give me death" style:
Dear XXX,
I'm a voter, taxpayer, parent, and online gambler....
worst thing you can do is say that you would've, should've, could'ved if this bill passes in a few months
