Well, I would think so, from what I follow of Eurovision. I am thinking that many of the people that run, plan and organize it are members of the LGBT community, just like here in the USA. There are at least two cable channels dedicated to LGBT friendly programming. You have to remember, they are demographically, a high income group and advertisers see them as valuable consumers.
It’s the same in New Jersey with LGBT moving into your town. They increase the value of their homes and buy high priced real estate. This drives up local property values overall and increases the property tax base. In NJ, local school funding is heavily dependent on collection of property taxes, so the rich town have the best schools. The poor towns often have terrible schools. That drives down property values even more, so it is a vicious cycle.
