Dealing with an oppositional toddler doesn't mean you're a dismissive parent. You can be as in tune as possible with your child's emotions, and they'll still have plenty of moments where they'll scream at you and refuse to do something just because you asked them to do it.
Learning how to convince them to do something in a way that they're amenable to is practically the opposite of being dismissive. You're not minimizing how they feel, you're just working towards a goal in a way that suits both people. Being a dismissive parent would be continuing to go down the same paths that lead to fighting, because clearly you don't care about how your child feels about it.
Many years, ago, early morning routine. I needed to go to work, so I just just told my then 3 1/2y old daughter she couldn't go to kindergarden right now, we go a little later.
Stamping her foot, "Nooooooo, I want to go now"
"Ok, if you insist...."
(That was in the "learning to say no" phase when she said "no" to everything for a time)
The key is not trying to trick them. Acknowledging their feelings as valid, helping them identify what they are feeling, and help them soothe.
A dismissive parent doesn't have to ignore a child. Just dismiss that child's emotions as irrational or not helpful. They might use distractions or tricks which may limit the ability to do the above.
At the end of the day, tricking a child is not a good parenting style even though it can be cute and even funny.
I answered this in other comments in this post already and don't want to spam. But basically children are capable of logic and you can convince them to do things without tricks or distractions.
