I think your passage may be much better written in this way:
I do not agree with the idea that pre-set numerical targets for gender parity should be applied to university admissions. I understand that this idea has been proposed by some as a measure to counter gender discrimination and to achieve gender parity.
"Bring up" or "brought up" is not correctly used in your original.
If I may say so, the whole passage does not "read English" at all.
You also need to learn the topical vocabulary for this subject before you can write about it well.
