As a member of traditional mosque, and a loser by many of Weatern societies standards, one of the things I like is the inclusiveness and the spirit of brotherhood. I think with women in the mosque, especially with liberal dress codes, there'll be cliquishness and sexual tensions. I read that with the Westernisaiton of Tibet, there emerged a class of cool kids, aloof from the losers, dressed in all the right gear, with the women, the goods etc.
Part of the social neuroscience for me in a traditional setting is that we're all engaged together as one in salat (worship) with a collective focus on God, not on the girl in front etc. Although I accept the legal right in Germany for such a mosque, I don't think it will have the spiritual or psychological relaxation of a traditional setting. Not for my type.
My mosque may seem like a "mens culb" though, for the outsider. I don't know what to say to that, excepting I can appreciate what I know, and am doubtful that Id have the same experience in a mixed liberal setting.
And [mention, O Muhammad], when Allah took a covenant from those who were given the Scripture, [saying], "You must make it clear to the people and not conceal it." But they threw it away behind their backs and exchanged it for a small price. And wretched is that which they purchased.
I avoid all kinds of trendy eateries... where I sense egotistic indulgence and standards for inclusion like what is your IQ, what degree you have, whos who, who you know, what age you are, what job you have etc. This for me is part of the pusrchacing power of secular liberalism at present. The GDP of the spirit of the age. Noise, clamour and chit chat.
The mutual rivalry for piling up (the good things of this world) diverts you (from the more serious things)
The psychologist J Haidt argued in "The Happiness Hypothesis", iirc, focus on absolute well being, not keeping up with the Jones. In that sense a Traditional mosque is a bit like meditation and yoga, where these psychological absorbtion.
Verily, the Promise of Allah is true, let not then this (worldly) present life deceive you, nor let the chief deceiver (Satan) deceive you about Allah.
In Islam there are bound up concepts of tranquillity, sincerity and certainty. With all those female distractions, I think that there'll be a lack of focus, harming sincerity in the religion. Its dependent on the tranquillity, like a smooth ride needs a smooth road. Muhammed said the softeness (or pleasure IIRC) of his eyes was salat i.e. prayer.
I don't know much about feminine psychology, but there's one song (by The Weather Girls) called "Its raining men" where the ideal "has gotta be strong, gotta be tough and gotta be fresh from the fight". That's against the Islamic ideal as a rule. Islam is more of a strategic religion, not a brut force method. In a mixed setting...
"Liberal mosques" seem like a cultural projection of an elitist enlightened political set, who 'know better' how to run things. Rather than a grass roots movement from the bottom up, its a top down thing, liberalism from above. They'll probably have a good vibe for some people, I'm not denying that.
For a Muslim, the closest we come to paradise is in the mosque and the closest we come to Allah is in sajda (prostration).
Verily in the heavens and the earth are signs for those who believe
