"I don't get the negativity towards the OP/this thread"
Well, the issue is that's it's quite simply unacceptable to bully or guilt-trip other people into having medical screening. If she'd phrased it differently, or posted it as a reminder to those who do choose to engage with the cervical screening programme then it would be different, but telling other women what should happen to their vaginas is absolutely not on. Ever.
If it's not in your knickers, it's absolutely none of your business what happens to it. Deal with it.
