So, then, what do we do in the face of such determination to deny not just our faith, but the very existence of a Man who lived and died (and--my vote here, because we all get a vote--rose again!) for the very people who seek to obliterate him from history? I can tell you right off what Christians too often do in these situations: Get angry. Open the door to outrage. Promote bans and boycotts. But generally that ends up being counterproductive, and too often fuels the fires of conflict.
Instead, how about a different tack?
1. Get On Your Knees. How often have you heard people say, "Is there anything I can do besides pray for you"? Friends, there's nothing more powerful, more life altering, than prayer. Take this whole crazy thing to the only One who truly understands it. Seek His wisdom. His guidance. Seek His mercy for these folks who--again, my vote here--are the ones who are truly deceived. Let time with Him fill your heart and mind with truth and peace and, above all things, His love and grace. Because those are your best weapons in this kind of battle.
2. Get Informed. Find out for yourself what these people are saying, and then commit yourself to learning what is and isn't true. The truth is there, we just need to seek it out. To study both Scripture and other historical references to Jesus. One of the criticisms/complaints thrown at Christians most often is that we're a people of experience rather than study or knowledge. As much as I hate to say it, I've found that to be true, both in myself at times and in other believers. Too few of us really apply ourselves to study of God's Words or to study of history. So let's put that criticism to rest. Take the time, even if it's just a short time each day, to really educate ourselves on the facts. Because when you're armed with facts and truth, your response can be balanced and filled with grace. And that's far more productive and, to my way of thinking, godly than outrage.
Want a good place to start reading in Scripture? 2 Timothy is perfect for times like this. I encourage you to not just read it, but study it. Find the deeper truths not just for yourself, but for that dark and angry world all around us.
As for the historical support that Jesus lived, here are a few sites where you can find information about the historians and what they had to say. I don't agree with everything these sites say, but they do offer some good information for getting started.

2. Get Ready. When your heart and mind are focused on Him, when you've done your part by studying and learning as best you can, be prepared. Odds are good doors to discussion will open. Whether with those you know or total strangers, take Paul's words to Timothy to heart:"
"I solemnly urge you in the presence of God and Christ Jesus, who will someday judge the living and the dead when he appears to set up his Kingdom: Preach the word of God. Be prepared, whether the time is favorable or not. Patiently correct, rebuke, and encourage your people with good teaching.
For a time is coming when people will no longer listen to sound and wholesome teaching. They will follow their own desires and will look for teachers who will tell them whatever their itching ears want to hear. They will reject the truth and chase after myths.
But you should keep a clear mind in every situation. Don’t be afraid of suffering for the Lord. Work at telling others the Good News, and fully carry out the ministry God has given you." (2 Tim. 4:1-6)
