You were not forced to change YOUR definition nor are you forced to embrace anything. God gave us brains to think for ourselves.
As for all the mentioning about how same-sex marriage was voted down by public votes, this is an issue that never should have been voted on in the first place. Would anyone here support a bill that would put the issue of banning Catholicism up to a vote? Of course not. Because our religion is between us and god. One being Catholic does not affect one who is an atheist, or a Baptist, or Jewish. In that same vein, the government allowing same-sex couples to enter in to a marriage “contract” does not affect those who do not wish to enter into said contract.
Now, I know I will be met with a dozen responses saying how gay marriage will lead to this and that. The majority of these arguments are simply based out of fear, or things that have nothing to do with the vast majority of gay people who enter into a civil marriage. If one wants to argue about “gay relationships” being talked about and public schools, or a florist and Baker being sued, that is a separate issue. Something should not be banned simply because a few extremists within that community go out of their way to make life harder for others.
