One aspect that particularly bothers me when it comes to religious attitude vs philosophical attitude is a certain judgement of those who disagree with you. If I disagree with someone philosophically, the most judging I can be is to say that I believe he/she is seriously mistaken and that his/her views would bring great harm. However, if I disagree with someone religiously, as in, the other person is not of my religion, I'll believe, implicitly or explicitly, that the disbeliever is somehow inferior in the eyes of God, that the nonbeliever is not worthy of the fruits of afterlife that are reserved for the believers of my religion, that even though I may respect you in this world, I believe that your very disagreement renders you deserving of an infinite punishment in hell, and that the very fact you cannot see the obvious truth of my religion and cannot take it on faith, you are somewhat of an imbecile. It might make some sense to say that the judgement of afterlife would be based on moral behavior of a person regardless of religious affiliation, but what sense does it make to say that the judgement of afterlife would first be about adherence to the true religion (i.e. my religion) based on faith and only afterwards moral behavior (and that too moral behavior as prescribed by my religion)?
As a philosopher, I recognize that there is almost always room for rational disagreement; perhaps no issue in metaphysics or ethics warrants universal agreement. It would be absurd to judge someone for not taking on faith something that is not rationally binding. How can I judge someone who disagrees with me on an issue on which legitimate rational disagreement exists? I can't, and I won't, and I cannot approve of an attitude which does so.
