Build a psychological bridge for buyers to walk over so that they will be open to hearing your response. Sometimes that seems to be so, only it isn't. X is actually one of its best points. Then, you give your answer to the objection or concern. After your answers, check back for buyers' thoughts and reactions.
Bridges lead to dialogue.
Bridges allow you to stay agreeable with buyers, which is not the same thing as agreeing with the buyers' objections. Remaining agreeable rewards you with the opportunity to change buyers' thinking. Becoming adversarial kills that chance. Avoid them at all costs. However, when caught, make sure you know how to escape.
