The French have a saying..."Plus les choses changent, plus elles restent les mêmes", which means, the more things change, the more they stay the same.
In the modern world, I'm not sure its entirely accurate, but in very general terms I think it stands.
Whilst its only right and proper that there is more "inclusivity", and less "negativity", I'm in favour of people being allowed to express their "preferences" in whatever language they choose....it's a great filter, I dont want people to be able to use guidelines as a way of hiding who they really are, and what they really think. As an example, if someone is a bigot of some kind, let them feel free to air their views, it will enable people to see them as they really are, and educate/avoid/ignore them. The greatest danger is in driving this sort of attitude "underground", where it festers and grows.
Swinging is becoming more mainstream, that in itself will be both a positive and a negative. Will swinging be "different" in the future? Absolutely, but I'm willing to bet it wont be much different, people will still go to clubs, parties, socials, and 1-2-1 meets.... but will pay lip-service to "social distancing", masks, and asking if others have had their jabs etc. The base desire to indulge will overcome any reticence.
