Very disturbing

Re: Very disturbing

You still did not answer my question. Sir, ethical and unethical depends on the set of values centric to your belief. You find it unethical because your belief is not based on the values and rules of Islam. When adopted sons reach puberty then their step mothers are supposed to observe hijab in front of them and all the rules of na-mehram apply. Perhaps it would be prudent to first understand what rights and responsibilities there are between those who adopt people and the adoptees. This is per Quran. So if you can marry another muslim brothers (as all muslims are brothers to one another) divorced wife then there is no difference. It is not unethical but if you say it might be socially unacceptable today I can buy that argument and even say that due to the social pressures of today I would do my level best to avoid such a thing if I ever ended up in it and simply refuse to do so. Your misunderstanding stems from your neglect of the differences in adoption in Islam and other cultures.

No one is telling you to go do this but just don't declare it haram when it is not.
