I am not a Moulana , kindly speak with respect , not with sarcasam.
The hadeeth was declared weak much before you posted here. 72 is a small number , if you go by weak hadeeth. There are hadeeth which shows the number to be even 4000 . The issue with that hadeeth is in chain of narration there is an unknown narrator . A person whose identity cannot be verified cannot be accepted.
What is known from authentic hadeeth in Muslim is that a person will have two wives. There is also mention of hoor in Quran , we do not know exact number .
A martyr getting damsel in Paradise is part of other religions as well , not just Islam. If someone is given that reward , what is your issue with that? Here also a man can have four wives. There are men around the world who have multople affairs . There women are called concubines , which is okay with you , but when a woman is called wife and is given all rights , you have an issue !
Men or women will have whatever they want conditional to what Allah swt has made them. I give you an example , if I want to become God , that is not going to happen. In world also we have restrictions on all our rights , there is nothing called unconditional rights.
