This should be self-evident.
If you are a prolific tweeter, and yet cannot find the time to tweet a single defense of the nation you claim to love against its many critics, then you cannot claim to be "pro-Israel."
If you cannot write a single tweet saying pointing out the absurdity of Israel-haters calling Israel an "apartheid state," then you cannot claim to be "pro-Israel."
If you cannot compose a single tweet about Israel's beauty, culture, history, or accomplishments - then you cannot claim to be "pro-Israel."
So if you aren't pro-Israel and every single one of your Israel-related tweets is critical, what are you?
