Perhaps it isn't your intent, but what you express is in effect that you value not keeping friendships with people when two conditions are simultaneously met 1. You are not sexually attracted to them. 2. They are likely to be sexually attracted to you.
The implication of this is for example, an exclusively heterosexual male would not maintain friendships with women he is not attracted to, nor possibly with homosexual or bi men.
I'm not putting words in your mouth, but just drawing out how your principles are realised in their application.
For he most part I agree with that approach in terms of avoiding difficulties of the other person being potentially left with feelings I cannot reciprocate. On the other hand, there's a sense that friendship is valuable enough a thing, to risk the other person experiencing the difficulty of unrequited attraction, but only if they are willing to endure that, and if i think I can be supportive of that struggle, should it arise in them.
idk, it's all a bit fraught for me, because maintaining my solitude and detachment is sometimes hard work, and adding more emotionl burden can get too much, and I just react by doorslamming people whose demands exceed my abilities.
