Easy to say but that's not so simple. You should still conform on the Constitutional laws of course 
. You can't just act like an alpha male and fuck whoever you want. It's our obligation to be humane.
Yet you still have your basic human rights. As far I remember, slavery have been abolished a lot of time ago. If some legislative norm is illegal then you're not obliged to follow it.. You can't just act like an alpha male and fuck whoever you want. It's our obligation to be humane. Though you can become a subject of prosecution, that may be a real problem in some cases.
aside from Islam since they're allowed to have more than one wife
Yep, but such kind of behaviour is not recommended.Quote
Ash-Shirbeeni from the Shaafii School of jurisprudence, said in Mughni Al-Muhtaaj: It is a Sunnah not to marry more than one wife if there is no apparent need.
Quote
Ibn Qudaamah may Allaah have mercy upon him from the Hanbali School of jurisprudence, said in Ash-Sharh Al-Kabeer: It is more appropriate to marry only one wife. The author of Al-Muharrar [i.e. Abul Barakaat Al-Majd ibn Taymiyyah] said this, based on the saying of Allaah (which means) {...But if you fear that you will not be just, then [marry only] one}.
