The same thing RCs are doing in trying to correct us. One could ask, what right did common Bereans have to examine the preaching of the apostles by Scripture?
If you’re not a Catholic what gives you the right to say anything about the Catholic Church? Criticize your own faith and clean it up. - NKP_Vet
We are not the ones promoting one elitist church despite it being a glass house that is overall liberal while throwing rocks at evangelicals.
While RCs presume they have the supreme authority to judge others, even though Scripture is not their supreme authority, we who hold it as such can engage in interpretation of what the magisterium says (which RCs also do) because God gave us the ability to do so, and the commission to reprove error, presuming we have repented of our personal sins.
And have no fellowship with the unfruitful works of darkness, but rather reprove them. (Ephesians 5:11)
Moreover, your "how dare you presume to correct us" attitude is essentially the same line used by the Jews and Pharisees against those who dared reprove them Scripture, but the church did not begin under the premise that the magisterium had indisputable authority, but was established upon Scriptural substantition in word and in power.
