It is also used by we Jews. We will.continue to do so.
A few remarks:
1) So you presume to speak on behalf of all Jews? On whose authority?
2) If you're Jewish, then why do you care about Christian opinions regarding their preference for BC/AD over BCE/CE? (After all, even Jews used Latin historically, such as Hillel ben Samuel. Was he honoring the destroyers of Jerusalem by using Latin?)
3) Given that the line of demarcation for BCE/CE is the same as BC/AD (the birth of Jesus Christ), it is a distinction without a difference. It would be akin to someone protesting the use of the Torah if they didn't rename it to "Five Books of Ancient Israel's History": even if you remove the religious flavor, the religious substance remains.
