It's being referred to as "public property", but in terms of property, is it "public" as in taxpayer funded?, or public as in "they own the property, but offer a service to the public"?...big difference between the two things.
One means that all taxpayers chipped in, and thus all should have equal access to use it (IE: Libraries, roads, hospitals, etc...)
The other means that it's a privately held business, that happens to offer services to the public, like a store, and thus should be able to refuse service to anyone they so choose, without even giving a reason quite frankly...
If it's the latter of the two, then them refusing to do business with someone who's engaging in something they disapprove of is 100% their right...much like it's the right of McDonald's to tell me that they refuse to serve me if I'm barefooted (The no shoes no service sign)...if I walked into McDonald's tomorrow, barefooted, claiming that it's part of my religion called "Barefootism" (which religion is a protected class), and they refused to serve me, would people here support the idea of the state of Ohio fining the restaurant $10,000???
People seem to have a double standard on this topic...there are certain things that our constitution protects, however, you give up certain things when you enter someone else's private property, for example...the 1st amendment protects my right to voice my opinions about people...even in a rude way if I so choose. However, if I'm in someone else's store or home and start yelling "Group XYZ is nothing but a bunch of scum!!!" (with some profanity peppered in) loudly, the property owner has a right to tell me to leave...I don't get to come back and sue them for violating my first amendment rights. If a store puts up a "no firearms" sign in the window, I don't get to sue them for violating my 2nd amendment rights... If a private club only allows men to be members but not women, they don't get to sue the club for violating their 14th amendment rights. etc... etc...
Like I said, it's all about private vs. public property and whether or not the company is privately held or has gone public.
...but like another poster mentioned earlier in the thread...it does seem fishy...they already found another place to marry them so it does sound like maybe they got their honeymoon paid for by playing the system here.
