Christian holidays

Okay so this has had me so mad for quite a while. So I have always been taught through religious means and I strongly believe in Christ and Christianity. I also do not understand why people celebrate Christian holidays, who do not believe in Christianity. Like Easter especially. Honestly I believe it is hypocritical. We Christians do not go around celebrating holiday that are not our religion? I find it disrespectful to God and Christ himself. I know some people will say bc it is now changed and people celebrate it as different means but I do not think non Christians should "celebrate" Christian holidays. They are days for Christians to celebrate Christ our Savior.  That's all I have to say and I know this will have many crazy comments but I honestly do not care. It is what I believe and it is what I am going to stand up for.
