Liberal Humanism vs Islam

I am very much at a crossroad. Every day I am faced with the inevitable clash of ideologies and belief within me; Islam and liberal-humanism.
I admit that I feel sceptical sometimes about where Islam stands at certain issues.

It is stated very clearly in the Quran that Allah ( and I mean Allah, as in the One True God not the appellative noun “God) forbids homosexuality. But it is hard to accept this when some of your friends have the alternative sexual orientation. And when you are forced to confront the inevitable clash of ideas, you are reluctant to voice out your disapproval in intellectual terms because (in truth) personally, I do not see any danger to society at large if homosexuality is tolerated. And so the dilemma comes into play. In terms of my faith, it is clearly wrong. In part, I am bound by my faith to say this, nay to believe this. But personally, and this is where the dilemma happens, I think it is quite alright.

Next is an issue very close to Muslims around the world; the Israeli-Palestinian conflict. I just got back from an Islamic program that I attended. Some of the talk that they had was on the Muslim’s responsibility to defend the Palestinians at all costs. I understand this perfectly. But there were a continued flow of negative rhetoric against the Israelis. This is the danger when one generalises and simplifies complicated histories and political situations. I think that there are not enough efforts being put to understand the plight of the common Israeli person. I do admit and believe that the Palestinians suffer much more than the Israelis but usually talks and articles that I have read are grossly anti-Israeli. When history is generalised and complicated political information become propaganda for certain quarters, we (the common man no! The common person) lose sight of what is the reality. After continued barrage of anti-Israeli adverts, it is unsurprising that one might even go so far as to approve rocket retaliation by Hamas to public places in Israel because it is implanted in our subconscious mind that ALL Israelis are terrorists. (it is my opinion that all forms of violence and usage of weapons greatly stalls the hope for peace in the Middle East even if it is in retaliation. When will it stop then? One side must be the better side and stop first, retaliate NOT. Retaliation is merely veiled revenge. Revenge never leads to peace.)
And I am aware that on these two issues, there are a multitude of different opinion within Islam. It gets very confusing.
And countless many issues at hand. At the end of the Islamic program that I went to in Glasgow, many of my friends were adamant in that they will work hard for the da’wah of Islam. And i do want to do da’wah but deep down, I envy these people for their fervour and unwavering faith. I am not saying that I am losing my faith in Islam. You see, from the very beginning, my belief in Islam is purely based on faith, not much knowledge is involved. Now that I am faced with contradictions between Islam and what I think is right in my mind, I found that faith alone is not enough for me to hold onto my beloved Islam. I need to learn more.
