You know what happens if you are not loud and active in making sure everyone knows and cares that you are LGBT+? That everybody will know and care that you are heterosexual. Because that's still society's default setting. What society expects you to be and projects upon you. When I was young(er) I felt more uncomfortable when everyfuckingbody asked me when was I going to get a girlfriend than I was when I started drawing attention on my being gay at the pride demonstrations. If you don't like the pride you are free to not go, of course. But pride is necessary for a lot of people. Critisising it as a non-participant comes accross as demobilising because the criticism of pride is exactly the same every year since it started, and people lose a lot of energy jumping back a couple of decades to address an already addressed issue.
