Hot Take: Sparity upsets me

Am I the only one who finds Spike X Rarity art to be... Problematic, to say the least? Spike is a literal baby, and Rarity is a grown mare with her own business. By the time Spike is a mature adult, Rarity would be a much, MUCH older mare due to how slowly dragons age. Yes, Spike is the one initiating it and has the obvious crush, but if you saw a child who said he wanted to marry his teacher and the teacher actually agreed to it, it would be a problem, wouldn't it? So seeing Sparity as such a popular ship unnerves me a little. Anycreature else who would agree with me here?
