Well, tone is a matter of opinion. If you look back at what I wrote I merely said that in my opinion you were overthinking this, you should wear what you want and do what you think best, and move on with your life. If that’s rude to you, I am sorry. It is the same advice others have given.
I do note here and in your other post that you seem sure your co workers are hostile, or angry, or unpleasant, and that they will be the same when you return. Maybe they are but try to see them in a more empathetic light, or at least make room for the Holy Spirit to act to change the situation. Try to see their virtues only, not their defects.
