On the contrary Scotus argument in his Treatise on God and First Principle relates the First Cause and Final causes to God who is also Trinity and that the causing arises for the sake of the Beloved (which is Christ). That is not Deism that is Trinitarian love and Scotus goes on to link The First Cause with arguments as to why God is Trinity and Being in relation to love.
Secondly if people don’t find arguments for God in any way compelling then the the devil and heli is also laughable.
For me God is first and foremost relational in love, which is what we need. Scotus arguments about God are all about a loving will that acts and not deism that just starts things and then does nothing. It may be that taken in isolation an arguments for God’s existence may be taken as deist but only if they are used in isolation from the rest of a defence of Christian doctrine.
