Your post neatly sidesteps the historical reasons for these marches taking place, the effect they have had and are continuing to have on the Catholic minority, and the cost of allowing them to go ahead in their present form, both in providing policing and in the risk they bring to life and the wellbeing of the communities affected.
They are weapons of sectarianism and by ignoring this fact you are condoning that sectarianism - for all your high-sounding protests.
