Of course everybody can celebrate a "wedding ceremony" but it is maybe not legally protected.
And somebody will point with the finger on you and they say of course stupid stuff.
Other people care and get hurt of these things and it is not right during the 21 st century.
I think gay people should have same rights and should not be seperated from so called the "normal" couples.
But I have to add that I do not think that you doubt this. I think you are living in Germany for quite a long time maybe
and of course here (in germany) marriage is also seen today of something you do not have to do just because of a
piece of paper and it is totally accepted.
