Specifically, what would they NOT have with a civil union that a married couple has? I've never read anything to indicate that a civil union was really any different from marriage. Only the names have been changed to protect the innocent.
There's issues like joint insurance that they are complaining about that they can't get- spousal benifits & such, Tax perks for married couples & such- however, there are workarounds to practically all these marriage perks already- but that isn't good enough for them- they want EVERYTHING married couples enjoy without having to do the workarounds.
Kattieanna- yep- it is quite disgusting
