The comment you're responding to didn't formulate the argument as "I am against [X], therefore I am justified in destroying property used to do [X]", but is rather closer "[X] is itself illegal and therefore I am justified in potentially destroying property in order to stop imminent lawbreaking".

You can argue the point as to whether this particular "[X]" actually does constitute illegal activity that a citizen is justified in responding to with force, but I don't think it's valid to mischaracterize the argument as the response being justified solely by personal opposition.
