Are “Ought” statements automatically dubious when used in Non-Evaluative Statements

I understand this is the Is-Ought Problem and I’ll give what I think is an example.

person 1 makes the Normative Statement Person 2 makes the Positive Statement 

1. The Filibuster is good Because it forces two sides to work together and can prevent majority rule or implementation of Autocratic powers. 
2. The Filibuster has effectively made the United States senate paralyzed as important bills have been killed outright or completely reduced to nothing to what it originally was intended. This has lead to both sides literally not passing bills that both sides agree on purely out of spite and created an environment where any controversial bill has no chance. This gives voters little way to judge how certain policies has had an effect on society. As nothing being agreed upon can be seen as one side not compromising or another side just being incompetent.
