Whoa, you appear to be one very angry young lady.
I will not draw on your actual case as it would be wrong to comment on what you say about your parents (a) not knowing you and (b) not knowing your parents and finally (c) not being able to verify both sides of this argument.
I am not naiive or in conflict with my kids or in denial. I am a lot older than you so I suppose you’ll write off my opinions as dated and useless.
You comment that your parents have never had your lifes’ experiences. Sorry but at your age you have not had any life experiences. All you have had until now is childhood and teenage years.
You are at a vulnerable and impressionable age and this is where maturity of age comes into the equation. Older folk see beyond what you are seeing right now. For example; You see the family car as old, cranky and an embarrasment to be seen in or drive. We see the car as a means of getting to A – Z quickly and comfortably. We own it and can afford it. You don’t and can’t!
There is nothing wrong with listening to what your parents have to say without interpreting it negatively – you won’t get anywhere with that attitude and it’s childish. Cildren feel when they reach a certain age it allows them to overide anything their parents may have to say on any matter.
Fact: No parent will force a child into a marriage they say is perfect for them and that the child does not want.
Fact: Most parents will try to draw from the child’s form of education, school, sem/yeshiva, chinuch in the home, hashkofa etc to make some form of conclusion as to what MAY (note the word may, which means possibly not definately) be suited to their child in regards to a shidduch.
That all said, along the way there may well be arguments such as: I want a learner for minimum ten years (and who will fund this??) or I want a clean shaven, kippa sruga guy / a girl who not cover her hair (Oi Vey, but our family all wear shtreimels/hats on the shetel).
There are many reasons as to why parents feel a shidduch is unsuitable. So act like an adult, and talk to them, explain the direction you wish to move in do not discuss these things with your friends who are as young and impressionable and opinionated as you.
