Quote from Myuym
Then would it be ok to ask about her opinions on recent news? Or otherwise asked what would be good topics without making her feel cornered (Seeing as I normally ask about religion and views on life really soon)
The reason why they are saying that "asking about religion and views on life" makes a girl feel cornered is because a lot of people consider those to be "profound topics" (maybe because they take a couple more braincells to process than the tripe most people talk about).
That immediately sets the tone of discussion to be more serious. In other words, you're already partially admitting that you're seriously considering her as a potential partner.
This, IMO, is acceptable when you're set up on a blind date, or you had prior arrangements with a girl, such as through online personals/matchmaking/dating, when the *context* of the situation is obvious: You're both looking for a partner, and it's reasonable to know about each others stances on these supposedly profound topics.
However, for a casual approach, the assumption is that no such admission/context is given. You're immediately shifting from a casual context to serious one. Giving the girl no time to prepare, "cornering" her.
