It is not "our-way-or-the highway". Lay Anglicans are not required to accept all aspects of church doctrine as a condition of membership.
If a member becomes a parent, infant baptism becomes a question of practice, rather than doctrine. Here again, though, refusal to have your child baptised would not lead to expulsion.
Most priests would be very happy to discuss it as a matter of doctrine, and might insist on discussing it if it becomes a question of practice (i.e.if you have a baby). They will be able to recommend books or other resources that may or may not convince you.
But you will not be expelled.
