1. I should be allowed to express my view without you always wanting to cap it with your view.
2. I should be allowed to express my view without your interference.
Are both sentences grammatically correct?
What is the exact meaning for 'wanting to cap'?
Does #1 mean #2?

"Wanting to cap it" does not seem exactly right to me. It either means:

Put your spin on my idea (i.e. flavour it with your idea).

Stop it being expressed fully by interrupting with your idea.


It's one of those two. I'm not sure which one.

The second example you gave is very clear.
