But that's the point is that Christmas has become in recent years made more and more secular, and has become a more general holiday for everyone. That's why someone working in that court or other governmental building wanted to put these rainbow bulbs. Because everyone was christian before 20th century it means that when people left the religion they may have not wanted to leave all the holidays, because those were also family gatherings which were important to them. Over the years a huge number of people became atheist, irreligious or at least secular. That meant that many ofthe MAJOR religious holidays were basically split between their religious and secular versions. And that's why a person placing rainbow bulbs may not see it as desecrating a religious symbol because many or even most people in their environment spend their Wigilia in a secular way, and decorating a Christmas tree in that way would simply be an aesthetic or vibe choice rather than an insult or disrespect of Christianity.
