That's ridiculous. Should I not use my surname because I identify my parents, my brothers and some of my cousins? I think bodily autonomy applies here.
You are giving far more away with DNA information; it's not remotely the same.
The point is, at the very least it's a grey area, so to dismiss the counter points so airily as you have done on such a serious subject indicates - at best - a lack of reflection and respect for the rights of others.
