Well if this manages to pass the senate then it will go on to the states and I believe every state but vermont has passed some sort of legistlation asking congress to get them this amendment.

The only way to prevent this is to mail(not e-mail) your senator a letter telling them how you feel on this and what you think and tell them not to do it(or do it depending on your stance). E-Mail doesn't work but hundreds of letters do work. If it is hand written it is even better.
